How to Write an Expository Essay | Structure, Tips & Examples

Published on July 14, 2020 by Jack Caulfield . Revised on July 23, 2023.

“Expository” means “intended to explain or describe something.” An expository essay provides a clear, focused explanation of a particular topic, process, or set of ideas. It doesn’t set out to prove a point, just to give a balanced view of its subject matter.

Expository essays are usually short assignments intended to test your composition skills or your understanding of a subject. They tend to involve less research and original arguments than argumentative essays .

When should you write an expository essay, how to approach an expository essay, introducing your essay, writing the body paragraphs, concluding your essay, other interesting articles, frequently asked questions about expository essays.

In school and university, you might have to write expository essays as in-class exercises, exam questions, or coursework assignments.

Sometimes it won’t be directly stated that the assignment is an expository essay, but there are certain keywords that imply expository writing is required. Consider the prompts below.

The word “explain” here is the clue: An essay responding to this prompt should provide an explanation of this historical process—not necessarily an original argument about it.

Sometimes you’ll be asked to define a particular term or concept. This means more than just copying down the dictionary definition; you’ll be expected to explore different ideas surrounding the term, as this prompt emphasizes.

Prevent plagiarism. Run a free check.

An expository essay should take an objective approach: It isn’t about your personal opinions or experiences. Instead, your goal is to provide an informative and balanced explanation of your topic. Avoid using the first or second person (“I” or “you”).

The structure of your expository essay will vary according to the scope of your assignment and the demands of your topic. It’s worthwhile to plan out your structure before you start, using an essay outline .

A common structure for a short expository essay consists of five paragraphs: An introduction, three body paragraphs, and a conclusion.

Like all essays, an expository essay begins with an introduction . This serves to hook the reader’s interest, briefly introduce your topic, and provide a thesis statement summarizing what you’re going to say about it.

Hover over different parts of the example below to see how a typical introduction works.

In many ways, the invention of the printing press marked the end of the Middle Ages. The medieval period in Europe is often remembered as a time of intellectual and political stagnation. Prior to the Renaissance, the average person had very limited access to books and was unlikely to be literate. The invention of the printing press in the 15th century allowed for much less restricted circulation of information in Europe, paving the way for the Reformation.

The body of your essay is where you cover your topic in depth. It often consists of three paragraphs, but may be more for a longer essay. This is where you present the details of the process, idea or topic you’re explaining.

It’s important to make sure each paragraph covers its own clearly defined topic, introduced with a topic sentence . Different topics (all related to the overall subject matter of the essay) should be presented in a logical order, with clear transitions between paragraphs.

Hover over different parts of the example paragraph below to see how a body paragraph is constructed.

The invention of the printing press in 1440 changed this situation dramatically. Johannes Gutenberg, who had worked as a goldsmith, used his knowledge of metals in the design of the press. He made his type from an alloy of lead, tin, and antimony, whose durability allowed for the reliable production of high-quality books. This new technology allowed texts to be reproduced and disseminated on a much larger scale than was previously possible. The Gutenberg Bible appeared in the 1450s, and a large number of printing presses sprang up across the continent in the following decades. Gutenberg’s invention rapidly transformed cultural production in Europe; among other things, it would lead to the Protestant Reformation.

The conclusion of an expository essay serves to summarize the topic under discussion. It should not present any new information or evidence, but should instead focus on reinforcing the points made so far. Essentially, your conclusion is there to round off the essay in an engaging way.

Hover over different parts of the example below to see how a conclusion works.

The invention of the printing press was important not only in terms of its immediate cultural and economic effects, but also in terms of its major impact on politics and religion across Europe. In the century following the invention of the printing press, the relatively stationary intellectual atmosphere of the Middle Ages gave way to the social upheavals of the Reformation and the Renaissance. A single technological innovation had contributed to the total reshaping of the continent.

An expository essay is a broad form that varies in length according to the scope of the assignment.

Expository essays are often assigned as a writing exercise or as part of an exam, in which case a five-paragraph essay of around 800 words may be appropriate.

You’ll usually be given guidelines regarding length; if you’re not sure, ask.

An expository essay is a common assignment in high-school and university composition classes. It might be assigned as coursework, in class, or as part of an exam.

Sometimes you might not be told explicitly to write an expository essay. Look out for prompts containing keywords like “explain” and “define.” An expository essay is usually the right response to these prompts.

An argumentative essay tends to be a longer essay involving independent research, and aims to make an original argument about a topic. Its thesis statement makes a contentious claim that must be supported in an objective, evidence-based way.

An expository essay also aims to be objective, but it doesn’t have to make an original argument. Rather, it aims to explain something (e.g., a process or idea) in a clear, concise way. Expository essays are often shorter assignments and rely less on research.

Expository Writing: Definition and Examples

By Hannah Yang

Table of Contents

What is expository writing, what is an expository paragraph, expository writing examples, how prowritingaid can help you with expository composition.

One of the most common types of writing is expository writing. Whether you’re a student taking an English class or a professional trying to communicate to others in your field, you’ll need to use expository writing in your day-to-day work.

So, what exactly does this term mean?

The short answer is that expository writing refers to any writing designed primarily to explain or instruct.

Read on to learn the definition of expository writing as well as some examples of what this type of writing can look like.

Before we look at examples of expository writing, let’s start with a quick definition of what this term actually means.

Expository Writing Definition

The term expository writing refers to any writing that’s designed to explain something. We use the word expository to describe any passage of writing that’s supposed to present information and help you understand it in an objective way.

Some common examples of expository writing include academic essays, textbooks, instructional guides, and news reports. Good expository writing should be factual, objective, and clear.

To better understand what this term means, think about the difference between a scientific article, a short story, and an advertisement.

The scientific article is considered expository writing because its primary purpose is to explain a particular topic in more detail. It presents data, analyzes what that data means, and focuses on the facts.  

On the other hand, the short story isn’t considered expository writing, because its core purpose isn’t to explain or inform—instead, it’s probably trying to entertain you or to take you on a journey. Short stories are narrative writing.

Similarly, an advertisement isn’t expository writing because its core purpose isn’t to explain or inform—instead, it’s trying to persuade you to buy what it’s selling. Advertisements are persuasive writing.   

Here’s a quick rundown of what expository essays should and shouldn’t do.

An expository essay should:

Teach the reader about a particular topic

Focus on the facts

Follow a clearly organized structure

Present information and details from credible sources

An expository essay should not:

Try to change the reader’s mind about something

Present the author’s personal opinions

Include made-up narratives or stories

Follow experimental or nonlinear structures

An expository paragraph is exactly what it sounds like—a paragraph of expository writing.

A well-written expository paragraph should follow a specific format to make it as clear and easy to read as possible. Most expository paragraphs do the following things:

Start with a topic sentence, which explains what the paragraph will be about

Then, include 3 – 5 body sentences that provide supporting details for the topic sentence

Finally, wrap things up with a closing sentence that summarizes what the paragraph has said

Writing an expository paragraph is a great way to practice expository writing. That’s because the paragraph follows the same structure as a more complex expository essay, just on a smaller scale.

Most expository essays should follow this format:  

Start with an introductory paragraph that includes the thesis statement, which tells the reader the core statement of the essay

Then, include 3 – 5 body paragraphs that provide factual evidence to support the thesis statement

Finally, wrap things up with a concluding paragraph that summarizes what the body paragraphs and thesis statement said

You can see the similarities between the two formats. If you can write a fantastic expository paragraph, you’ll be well-prepared to move on to writing a full expository essay.

Example of Expository Paragraph

Here’s an example of an expository paragraph that follows the structure described above.

The leading cause of death in the United States is heart disease, which can be fatal if it leads to heart attack or cardiac arrest. Heart attacks occur when a blockage in the coronary artery prevents oxygenated blood from reaching the heart. Cardiac arrests occur when the heart stops pumping entirely, which prevents the patient from breathing normally. Both of these problems can be deadly, even in seemingly healthy people who don’t have noticeable risk factors. As a result, heart disease is an important problem that many doctors and scientists are researching.

Good writing = better grades

ProWritingAid will help you improve the style, strength, and clarity of all your assignments.

There are many ways you can present information in an expository essay. Here are four of the most popular ways, along with examples of each one.  

Problem and Solution Essay

A problem and solution essay presents the reader with a problem and then considers possible solutions to that problem. 

Here’s an example passage you might find in a problem and solution essay:

Among the many proposed solutions to rising carbon emissions, one promising possibility is carbon trapping. Scientists are figuring out how to pull carbon emissions out of the atmosphere and trap it in less harmful forms, such as by injecting carbon dioxide underground so it will turn to stone.

Compare and Contrast Essay

This type of essay takes two subjects and compares and contrasts them. It focuses on highlighting the differences and similarities between those two things.

Here’s an example passage of this type of expository writing:

Though country music and R&B music have very different sounds, they also share many similarities. For one thing, both types of music embody a specific cultural identity. For another, both genres trace their roots back to the 1920s, when the Victor Talking Machine Company signed singers from the American South.

Classification Essay

In a classification essay, you describe the categories within a certain group of things.  

Here’s an example passage you might find in a classification essay:

There are three ways in which artificial intelligence might become stronger than humans in the future: high speed, high collective intelligence, and high quality. A speed AI would be able to perform calculations and experience the world much faster than humans. A collective intelligence, like a hive mind, would be able to break down a complex task into several parts and pursue them simultaneously. Finally, a quality AI would simply be able to solve more complex problems than humans could.

Process Essay

In a process essay, you give the reader the steps for completing a specific process. This is similar to a how-to guide or an instruction manual.   

Here’s an example passage you might find in this type of expository writing:

Caramelize the chopped onions in a frying pan. When the onions have caramelized, mix in the bell peppers, mushrooms, and tomatoes and stir for 4 – 6 minutes or until all the ingredients have softened. If you want to add meat, you can add ground beef and cook for another 4 – 6 minutes. Season with salt and pepper to taste.  

Good expository writing should be easy to read. After all, the purpose of exposition is to explain things to your readers, and you won’t be able to accomplish that if they have trouble understanding your writing.

That’s why ProWritingAid can help you write an expository essay. The grammar checker can help you ensure your sentences flow well, you’re not missing any necessary punctuation, and all your words are precise and clear.

Good luck, and happy writing!

What is an expository essay?

The expository essay is a genre of essay that requires the student to investigate an idea, evaluate evidence, expound on the idea, and set forth an argument concerning that idea in a clear and concise manner. This can be accomplished through comparison and contrast, definition, example, the analysis of cause and effect, etc.

Please note : This genre is commonly assigned as a tool for classroom evaluation and is often found in various exam formats.

The structure of the expository essay is held together by the following.

• A clear, concise, and defined thesis statement that occurs in the first paragraph of the essay.

It is essential that this thesis statement be appropriately narrowed to follow the guidelines set forth in the assignment. If the student does not master this portion of the essay, it will be quite difficult to compose an effective or persuasive essay.

• Clear and logical transitions between the introduction, body, and conclusion.

Transitions are the mortar that holds the foundation of the essay together. Without logical progression of thought, the reader is unable to follow the essay’s argument, and the structure will collapse.

• Body paragraphs that include evidential support.

Each paragraph should be limited to the exposition of one general idea. This will allow for clarity and direction throughout the essay. What is more, such conciseness creates an ease of readability for one’s audience. It is important to note that each paragraph in the body of the essay must have some logical connection to the thesis statement in the opening paragraph.

• Evidential support (whether factual, logical, statistical, or anecdotal).

Often times, students are required to write expository essays with little or no preparation; therefore, such essays do not typically allow for a great deal of statistical or factual evidence.

• A bit of creativity!

Though creativity and artfulness are not always associated with essay writing, it is an art form nonetheless. Try not to get stuck on the formulaic nature of expository writing at the expense of writing something interesting. Remember, though you may not be crafting the next great novel, you are attempting to leave a lasting impression on the people evaluating your essay.

• A conclusion that does not simply restate the thesis, but readdresses it in light of the evidence provided.

It is at this point of the essay that students will inevitably begin to struggle. This is the portion of the essay that will leave the most immediate impression on the mind of the reader. Therefore, it must be effective and logical. Do not introduce any new information into the conclusion; rather, synthesize and come to a conclusion concerning the information presented in the body of the essay.

A complete argument

Perhaps it is helpful to think of an essay in terms of a conversation or debate with a classmate. If I were to discuss the cause of the Great Depression and its current effect on those who lived through the tumultuous time, there would be a beginning, middle, and end to the conversation. In fact, if I were to end the exposition in the middle of my second point, questions would arise concerning the current effects on those who lived through the Depression. Therefore, the expository essay must be complete, and logically so, leaving no doubt as to its intent or argument.

The five-paragraph Essay

A common method for writing an expository essay is the five-paragraph approach. This is, however, by no means the only formula for writing such essays. If it sounds straightforward, that is because it is; in fact, the method consists of:

• an introductory paragraph
• three evidentiary body paragraphs
• a conclusion

Expository Essays Made Simple: The Guide With Examples

What is an expository essay?

How to write, structure, and format it to reach its purpose?

This article is here to answer all your questions on expository writing. I’ll share the meaning and provide a few templates and examples for extra clarity.

Expository Essay Definition

Examples of such explanatory texts are:

• Scholarly articles
• Instructional or technical guides
• Unbiased journalistic investigations
• A news report
• Business writing

It’s an expository text definition for us to understand the nature of this paper type. For more info, let’s learn the characteristics and elements of an expository essay.

What are the characteristics of expository essay?

Expository papers are factual and objective. They have a clear purpose, and their structure is linear and logical. In such essays, writers don’t share their opinions and don’t try to persuade readers.

Expository essays:

• Teach readers about the topic.
• Provide detailed information.
• Describe and explain facts.
• Clear, concise, and written with formal language.
• Organized, in the 3rd person, with precise word choice.

What are the elements of an expository essay?

• Strong thesis statement
• Evidence and examples
• Specific supporting details to explain the topic for a better understanding
• Logical structure and transitions between paragraphs
• Compelling conclusion to help readers remember the information better

What Is the Purpose of an Expository Essay?

The purpose of an expository essay is to present information and explain a topic. No personal opinions or biased statements are here, just facts with evidence.

The main focus is logic and coherence.

I’ve found the method for you to remember expository essays’ organization. It’s POET:

• P — Purpose: analyze, tell, explain, and connect the information.
• O — Organization: do research, outline, and structure your paper.
• E — Evidence: use facts, statistics, expert quotes, and examples.
• T — Thesis: be concise and straightforward.

Expository vs. Argumentative

An easy way to understand the meaning and purpose of explanatory papers is to compare them with other text types. Students most often confuse expository essays with argumentative (persuasive) ones. The above table demonstrates the differences for you to remember.

Types of Expository Writing

As a rule, teachers mention the type of expository essay in the assigned prompt. It helps you understand how to structure and present the information in your paper.

The five types of expository writing are:

• Definition. These papers describe and explain concepts. You just tell readers about something: a person, a place, a situation, etc.
• Classification. Here you need to break a broad concept into subcategories. Start with a general topic, and then tell about each subgroup. (Example: an essay about movie genres, cat breeds, book styles, etc.)
• Process (how-to). These texts explain to readers how to create or do something. Give instructions, steps, and practical tips. We also know process essays as problem-solution papers. A writer introduces and describes a problem and then tells the audience how to solve it.
• Compare-and-Contrast. Here you tell about the similarities and differences between at least two subjects. Or, you can describe the pros and cons of something. (Example: compare two novels of the same author; pros and cons of living in a village; etc.)
• Cause-and-Effect. These essays explain why something happened and what the outcome was. (Example: why Executed Renaissance (1) happened in Ukraine in the 1930s and what effects it has now.)

Expository Essay Structure

In academia, expository essays are standard 5-paragraph papers. You write an introduction, three body paragraphs, and a conclusion.

Below is more information on what to include in every paragraph.

Introduction

The introduction of expository essays includes the topic and the main idea. Three elements to write here:

• A writing hook to grab the reader’s interest
• A topic’s background (introducing the topic)
• A thesis statement summarizing the main idea (what you’ll tell about the subject)

Here’s an example:

Body Paragraphs

Expository papers have at least three body paragraphs, each exposing one idea. It’s critical to craft logical transitions between paragraphs and include evidential support.

Each paragraph should have a logical connection to the thesis statement. As for evidence, use statistics, citations, and other info you’ve got when researching. (2)

Here go your four E’s to consider:

• Explanations
• Elaboration

That’s what a body paragraph of your expository paper might look like:

Three elements to include:

• Topic sentence (to state what this paragraph will be about)
• Explanation of the topic in detail
• Concluding sentences with a logical transition to the next paragraph

The final paragraph restates the thesis, given the evidence you provided in the essay. Summarize the topic, but don’t introduce any new information. Leave readers with a positive impression of your work.

Three elements of expository essay conclusions:

• Readdressing the thesis in light of the provided information
• A brief overview of the essay’s key points
• The key takeaway for readers to remember from your essay

Expository Essay Format

Example of Expository Essay

Below is your example of expository writing to see the structure and format. It’s a standard five-paragraph essay students write in college. The number of words and paragraphs may differ depending on the prompt you get from teachers.

What is the primary purpose of an expository text?

The primary purpose of an expository text is to inform readers about the topic. Such texts describe and explain concepts to educate the audience. They are objective. A writer shouldn’t express personal opinions or attempt to persuade readers. Expository essays are descriptive, not argumentative or persuasive.

How to write an expository essay?

First, review the prompt; it will tell you all the instructions. You’ll know a topic, a word count, a format, etc. Then, do research and gather all the information about your subject. What will you tell the readers? What evidence you’ll use to support your points? Once ready, create an outline. You’ll need to specify the thesis statement and think about how you structure an essay. Finally, write a draft and proofread and edit it before submitting it to a teacher’s review.

What is typically included in the introductory section of an expository essay?

An introductory paragraph starts with a hook to grab readers’ attention to the topic. Then, provide a topic’s background for readers to understand what you write about. Finally, finish your introduction with a thesis statement. In the thesis, summarize the main idea of your paper.

How long is an expository essay?

Target about 800 words for expository writing. It includes five paragraphs: an introduction, three body paragraphs, and a conclusion. Check your prompt carefully: It often mentions the number of words to write.

Frequently asked questions about expository essay

Expository writing can be defined as a type of discourse that aims to present information, explain concepts, or explore ideas in a clear, concise, and objective manner. Its primary purpose is to provide a clear and objective understanding of the topic at hand. This means avoiding personal opinions, biases, or attempts to persuade the reader. Instead, the language used should reflect a neutral and informative tone.

When writing an expository essay, the focus is on supporting your points or claims with evidence rather than presenting arguments. The goal is to present a coherent and logical analysis based on the available information and evidence. This may involve using examples, statistics, research findings, or expert opinions to provide a comprehensive and well-rounded understanding of the topic.

Exploring engaging expository essay topics

Expository essays are commonly assigned to students, tasking them with thoroughly examining a particular subject and offering a comprehensive analysis. Whether you are given a specific topic or have the freedom to choose one, it is crucial to approach the planning process thoughtfully and engage in effective prewriting techniques for drafting the thesis and organising your essay.

Here are a few examples of different types of topics that are commonly encountered when writing an expository essay:

Example Expository Topic: Exploring the Causes and Effects

Investigate the causes and effects of air pollution in urban areas.

A good approach to this essay prompt is to analyse the factors contributing to air pollution in cities and explore its impact on human health and the environment. Additionally, provide recommendations for mitigating its effects.

Example Expository Topic: Understanding the Process

Explain the process of photosynthesis and its importance in the ecosystem.

In this example, providing a detailed explanation of the biological process of photosynthesis and highlighting its significance in sustaining life on Earth would be effective. It is also important to discuss the interdependence between plants and other organisms to provide a comprehensive understanding of the topic.

Example Expository Topic: Examining the Similarities

Compare and contrast different approaches to alternative medicine.

When addressing this topic, it is valuable to explore various alternative medicine practices, such as acupuncture, herbal remedies, and homoeopathy. Analyse their principles, effectiveness, and potential benefits and drawbacks in comparison to conventional medicine.

Example Expository Topic: Classifying the types

Classify different types of musical genres based on their characteristics and origins.

When approaching such classification topics, it is valuable to examine various musical genres, such as jazz, rock, classical, hip-hop, and pop. Explore their distinct characteristics, historical origins, and the cultural influences that shape each genre. Classify them based on common traits and highlight the diversity within the realm of music.

Example Expository Topic: Probing the Meaning

Define the concept of cultural diversity and examine its importance in fostering understanding and inclusivity in society.

When approaching definition topics, it is valuable to provide a clear and comprehensive definition of cultural diversity, emphasising the coexistence of different cultural backgrounds, traditions, and perspectives. Explore the benefits of cultural diversity in promoting tolerance, empathy, and mutual respect. Discuss examples and case studies that illustrate the positive impact of embracing cultural diversity in various societal contexts.

By brainstorming these topic examples and approaching them with thorough analysis and supporting evidence, you can effectively engage readers and provide them with valuable insights and information. Once you have collected the necessary facts, evidence, and key points for your essay, it is time to move to the writing phase.

Decoding the expository essay structure: Intro, body & conclusion

To effectively communicate ideas and engage readers, it is crucial to grasp the format and structure of an expository essay. The well-defined organisation of an expository essay allows for the logical progression of thoughts, ensuring that information is presented in a cohesive and easily comprehensible manner. By understanding and applying the appropriate structure, you can effectively convey your message, enhance clarity, and create a seamless reading experience for your audience.

The general format of the expository essay consists of three key steps: introducing your essay topic, structuring the body, and crafting a conclusion. Each step plays a crucial role in creating a well-organised and engaging essay. Let's explore each step in detail.

1 Opening paragraph:

When it comes to structuring your essay, the introduction paragraph serves as a vital starting point. It should effectively grab the reader's attention, provide context, and present the main idea of your essay.

• Grabbing the reader's attention: Use a compelling fact, quote, or anecdote hook related to your topic to pique the reader's interest.
• Providing context: Give a brief overview of the subject matter to provide necessary background information for the reader to understand the topic.
• Presenting the main idea: Conclude your introduction paragraph with a clear and concise thesis statement . This statement should succinctly outline the main purpose of your essay.

Let’s take an example of the topic “Examine the challenges and benefits of implementing renewable energy sources on a global scale.” for writing an introduction paragraph for the expository essay. Hover over to each underlined element for a better presentation:

Example of expository essay: Introduction paragraph

Did you know that renewable energy sources have the potential to revolutionise the global energy landscape? With increasing concerns about climate change and the finite nature of fossil fuels, the exploration of alternative energy options has become paramount. This paper examines the challenges and benefits of implementing renewable energy sources on a global scale, highlighting the potential for sustainable and cleaner energy solutions.

2 Structuring the body paragraph:

• Opening topic sentence: To ensure a well-organised and coherent essay, structure each body paragraph around a specific key point related to your thesis statement. Begin each body paragraph with an opening topic sentence that directly links to your thesis. This topic sentence sets the stage for the information and analysis to follow.
• Supporting evidence: After the opening sentence, it's essential to provide supporting evidence to strengthen your thesis. This evidence can include facts, statistics, expert opinions, examples, or quotations from credible sources. Make sure to cite your sources appropriately to maintain the integrity of your essay.
• Analysing the evidence: After presenting the supporting evidence, analyse the information and explain its significance in relation to your thesis statement. Provide insights, explanations, and interpretations to help the reader understand the relevance and impact of the evidence you have presented. This analysis should demonstrate your understanding of the topic and showcase your ability to critically evaluate the information.
• Transitioning between ideas: To ensure a smooth flow between paragraphs, include transitional words or phrases that connect one idea to the next. These transitions help guide the reader through your essay, making it easier to follow your line of reasoning. Some examples of transitional words or phrases include "Furthermore," "In addition," "On the other hand," or "Moreover."

Example of expository essay: Body

One of the key challenges in implementing renewable energy sources on a global scale is the initial investment required for infrastructure development. According to a report by the International Renewable Energy Agency (IRENA), the upfront costs of constructing renewable energy facilities can be substantial. For instance, building large-scale solar power plants or offshore wind farms necessitates significant financial resources. Despite the high initial costs, it is crucial to consider the long-term benefits. Renewable energy sources provide a sustainable and clean alternative to fossil fuels, reducing greenhouse gas emissions and mitigating the impacts of climate change. Moreover, as technology advances and economies of scale are realised, the costs of renewable energy infrastructure are expected to decrease, making them more economically viable in the future. Furthermore, the implementation of renewable energy sources brings additional benefits beyond environmental considerations.

3 Drawing a conclusion:

The last step in structuring your essay is the conclusion, where you bring your ideas together and provide a satisfying ending to your expository essay. To structure the concluding paragraph consider:

• Restating the Thesis: Begin the conclusion by restating your thesis statement in a concise and impactful manner. This reinforces the main purpose of your essay and reminds the reader of the central argument or idea.
• Summarising the Main Points: Provide a brief summary of the key points discussed in the body paragraphs. However, avoid introducing new information or going into extensive detail. Instead, focus on highlighting the main ideas and findings that support your thesis.
• Closing Thoughts: Conclude your essay with some closing thoughts that leave a lasting impression on the reader. You can reflect on the significance of the topic, discuss potential implications or future developments, or offer a thought-provoking question to encourage further exploration.

Example of expository essay: Conclusion paragraph

The exploration of renewable energy sources on a global scale holds great potential for revolutionising the energy landscape. Despite the challenges of initial investment, the long-term benefits of sustainable and cleaner energy solutions cannot be ignored. Not only do renewable energy sources reduce greenhouse gas emissions and combat climate change, but they also offer the prospect of economic viability as technology advances. Moreover, the implementation of renewable energy sources brings additional advantages beyond environmental considerations, such as job creation and energy independence. By embracing renewable energy, we can pave the way towards a more sustainable and prosperous future for generations to come.

By following this structure for your expository essay's conclusion, you can effectively wrap up your ideas and leave a strong impression on the reader, reinforcing the main points and leaving them with something to ponder.

If you saw the words “expository essay” on a writing assignment, would your mind draw a blank? Would you immediately feel as if you had stumbled into unexplored territory?

Well there's good news.

This post is written by guest writer Dixie-Ann Belle. You can learn more about Dixie-Anne at the end of this article. Welcome Dixie-Ann! 

You might not realize it, but chances are this is not your first encounter with this type of essay. Once you have been writing essays in academic environments, you have probably already worked on expository writing.

In this article, I hope to help you recognize this essay type and understand the expository essay outline. Comprehending the building blocks is instrumental in knowing how to construct an exceptional expository essay.

Lay a Strong Foundation

Over the years, I have taught and tutored college students one on one as they write academic essays, in face to face classrooms and online, and I have noticed a pattern. They often approach essays in one of two ways.

Some consider them with apprehension and are fearful of making mistakes. Others feel confident that they have written many essays before and think they have already mastered expository writing.

Interestingly, it's the latter who often end up the most shaken when they realize that they are not as familiar as they think with this type of writing.

What I hope to instill in my students is that they should not feel intimidated whatever their situation or essay assignment.

I encourage them to make sure they understand the foundations of the expository essay structure. I try to get them to grasp the basic blocks that need to be there, and once they do, they have a good chance of crafting a substantial piece of writing.

What is an Expository Essay?

Students are typically assigned one of at least four types of essays: the persuasive/argumentative essay, the descriptive essay, the technical essay, or the expository essay.

Writing an expository essay is one of the most important and valuable skills for you to master.

According to the Purdue Online Writing Lab:

The expository essay is a genre of essay that requires the student to investigate an idea, evaluate evidence, expound on the idea, and set forth an argument concerning that idea in a clear and concise manner.

Keep in mind that your expository writing centers on giving your reader information about a given topic or process. Your goal is to inform, describe, or define the subject for your readers.

As you work to achieve this, your essay writing must be formal, objective, and concise. No matter what your discipline, it's almost guaranteed that you will be required to write this common type essay one day.

Some expository essay examples could include:

• Define the term ‘democracy'
• Compare and contrast the benefits of cable television vs streaming
• Outline the process that generates an earthquake
• Classify the different types of tourism
• Outline the aspects of a good fitness program

The possibilities are endless with expository writing, and it can cover a wide variety of topics and specialties.

3 Building Blocks of a Great Expository Essay

To make sure you're on the right track with this type of paper, it helps to understand the three building blocks of the expository essay format and how to apply them to the final expository essay structure .

1. Write an introduction

Most students know that an introductory paragraph should grab the interest of the reader. However, they might not realize that it should also provide context for the essay topic.

Ask yourself : What are you talking about in this essay? Why is this topic important? Some background details could help to establish the subject for your reader.

For example:

If you were writing an essay on the impact smartphones have on society, you might want to start with some information on the evolution of smartphones, the number of smartphones in society, the way people use the phones and more.

The introduction should start off with general information.

You then work your way down to the more specific and principal part of your introduction and the crown of your whole essay, the thesis statement.

What is the thesis statement?

Your thesis statement states in concise language what this essay is going to be about. It is one clear sentence which expresses the subject and the focus of this piece of writing. If there is a prompt, the thesis statement should directly answer that prompt.

Our smart phones topic might create a thesis statement like:  Smart phones have many positive impacts for adults in the business world.

Right away the reader has some idea of what's ahead.

2. Write your body paragraphs

With your thesis statement clear in your mind and your introduction setting the scene, it is time to write your body paragraphs.

Each body paragraph contains supporting information including factual evidence for your essay topic. Each paragraph should each focus on one idea.

Depending on your word count and the teacher requirements, you can write any number of body paragraphs, but there are usually at least three for a basic five paragraph essay.

Each body paragraph should start with a topic sentence. A topic sentence is one single statement that explains the point of the paragraph. It directly refers to your thesis statement and tells you what the body paragraph is going to be about.

Remember our smart phone thesis statement? You need something that will relate to that thesis sentence and will alert the reader to what is to come.

Here's one possibility: 

Smart phones can help increase productivity  for professional adults.

This topic sentence not only reminds us that you are talking about positive impacts for adults with smart phones, it now shows us what the following paragraph will cover.

The best body paragraphs will go on to include different types of details, all of which would support your topic sentence. A good abbreviation to encapsulate the different details is spelt TEEES.

The TEEES Body Paragraph Structure

Let's break down this abbreviation and explore the types of details you'll need in your body paragraphs

T: Topic sentence

You'll begin with your topic sentence establishing the purpose of this paragraph. We'll use our example from above:

Smartphones can help increase productivity for professional adults.

E: Explanation

This is where you expand on your topic and include additional supportive information.

If you were talking about smartphones and productivity, maybe you could mention what elements of the smartphone make it optimal for productivity.

E: Evidence

This is the information from reputable sources you researched for your topic. Here's where you can talk about all the information you have discovered from experts who have carefully studied this subject.

For our smartphone essay, perhaps you could mention a quote from a technology reporter who has been following the rise of smartphones for years.

E: Examples

This would be concrete subject matter to support your point.

Maybe here you can list some of the smartphone apps which have proven to increase productivity in the workplace.

S: Significant/Summarizing sentence

This is the last sentence in the body paragraph which summarizes your point and ends this part of your essay. There should be no doubt in the reader's mind that you have finished talking about your topic, and you are moving on to another in the next paragraph. Here's how we could conclude this paragraph on smartphones and productivity:

Smartphones have transformed the productivity of the modern workforce.

3. Write the conclusion

Once you have written your body paragraphs, you're in the home stretch. You have presented all of your points and supported them with the appropriate subject matter. Now you need to conclude.

A lot of students are confused by conclusions. Many of them have heard different rules about what is supposed to be included.

One of the main requirements to keep in mind when ending an expository essay is that you do not add new information.

This is not the time to throw in something you forgot in a previous body paragraph. Your conclusion is supposed to give a succinct recap of the points that came before.

Sometimes college students are instructed to re-state the thesis, and this puzzles them. It doesn't mean re-writing the thesis statement word for word. You should express your thesis statement in a new way.

For example, here's how you could approach the conclusion for our smartphone essay.

You've come up with three points to support your thesis statement, and you've explored these three points in your body paragraphs. After brainstorming, you might decide the benefits of smartphones in the workplace are improved productivity, better communication, and increased mobility.

Your conclusion is the time to remind your reader of these points with concise language. Your reader should be able to read the conclusion alone and still come away with the basic ideas of your essay.

Plan Your Essay Based on an Expository Essay Outline

While writing fiction, it is sometimes okay to “pants” it and just leap into writing your story.

When writing essays in academia, this is rarely a good idea. Planning your essay helps organize your ideas, helps you refine many of your points early on and saves time in the long run.

There are lots of great brainstorming techniques you can use to get your ideas together, but after that, it's time to create a topic to sentence outline.

There are three steps to creating your topic to sentence essay outline.

• Develop a powerful thesis statement. Remember, this is the overarching idea of your entire essay, so you have completed a significant step once you have one done.
• Come up with the ideas you would like to support your thesis statement.
• Based on your points, craft your topic sentences.

Here is an example of a topic to sentence outline:

Having these important foundation details completed is a great way to develop your essay as you build on each part. It is also an effective method to make sure you are on the right track.

Depending on your instructor (or tutor, if you have one), you can show your outline to them to get feedback before you launch into your entire essay.

Even if you don't have anyone to provide a critique, the outline can make it easier to revise how you will approach the rest of your paragraph essay.

You now have some firm foundations to help you as you construct your expository essay.

How do you organize an expository essay?  Let us know in the comments .

Take fifteen minutes to practice writing your own expository essay.

First, choose an expository writing assignment topic. If you can't think of one, use one of the expository essay examples below .  

• What are the nutritional elements of a healthy breakfast?
• What are some of the most influential types of music?
• Compare and contrast the benefits of electric and gas cars. 
• What are the major steps to planning a stress-free vacation?
• How do smartphones affect mental health?
• Define true love.

Craft a thesis statement about your topic. Then, write three topic sentences for your body paragraphs.

With the time you have left, start writing your essay. You might be surprised how much you can write in fifteen minutes when you have a clear outline for your essay!

When your time is up, share your outline and your essay in the Pro Practice Workshop here . After you post, please be sure to give feedback to your fellow writers.

Happy writing!

Expository Essay

Definition of expository essay, types of expository essay, difference between an expository essay and an argumentative essay, examples of expository essay in literature, example #1: how chinese mothers are superior (by amy chua).

“I’m using the term ‘Chinese mother’ loosely. I know some Korean, Indian, Jamaican, Irish and Ghanaian parents who qualify too. Conversely, I know some mothers of Chinese heritage, almost always born in the West, who are not Chinese mothers, by choice or otherwise. I’m also using the term ‘Western parents’ loosely. Western parents come in all varieties. All the same, even when Western parents think they’re being strict, they usually don’t come close to being Chinese mothers. For example, my Western friends who consider themselves strict make their children practice their instruments 30 minutes every day. An hour at most. For a Chinese mother, the first hour is the easy part. It’s hours two and three that get tough.”

This is an excerpt from a comparison/ contrast essay by Amy Chua, which explains how mothers are different in different cultures. This paragraph compares mothers from Chinese, Iranian, Jamaican, and Irish contexts .

Example #2: Learning to Read (by Malcolm X)

“It was because of my letters that I happened to stumble upon starting to acquire some kind of a homemade education. I became increasingly frustrated at not being able to express what I wanted to convey in letters that I wrote, especially those to Mr. Elijah Muhammad. In the street, I had been the most articulate hustler out there. I had commanded attention when I said something. But now , trying to write simple English, I not only wasn’t articulate, I wasn’t even functional. How would I sound writing in slang , the way I would say it, something such as, ‘Look, daddy , let me pull your coat about a cat, Elijah Muhammad — ‘ Many who today hear me somewhere in person, or on television, or those who read something I’ve said, will think I went to school far beyond the eighth grade. This impression is due entirely to my prison studies.”

Example #3: Summer Ritual (by Ray Bradbury)

“About seven o’clock you could hear the chairs scraping from the tables, someone experimenting with a yellow-toothed piano , if you stood outside the dining-room window and listened. Matches being struck, the first dishes bubbling in the suds and tinkling on the wall racks, somewhere, faintly, a phonograph playing. And then as the evening changed the hour, at house after house on the twilight streets, under the immense oaks and elms , on shady porches, people would begin to appear, like those figures who tell good or bad weather in rain -or-shine clocks. Uncle Bert, perhaps Grandfather, then Father, and some of the cousins; the men all coming out first into the syrupy evening, blowing smoke, leaving the wSWomen’s voices behind in the cooling-warm kitchen to set their universe aright. Then the first male voices under the porch brim, the feet up, the boys fringed on the worn steps or wooden rails where sometime during the evening something, a boy or a geranium pot, would fall off.”

Expository Essay Guide

Whether you are a high school, college, or university student, the academic curriculum you follow will always include essay writing assignments. And expository writing is no exception. The importance of expository essays can’t be overestimated. Such papers, sometimes also known as informative essays , help students hone their critical thinking and provide unbiased information on a specific topic.

And although expository essays share similar characteristics with informative papers, they still have distinctive features. This guide sheds light on what expository essay writing is, what aims it carries, what types it has, and how to compose it.

What is an Expository Essay? – The Definition

An expository essay is a properly structured written piece that revolves around verified information and explains or describes something to the reader. It requires the writer to distance their own views from the topic and provide only verified and factual information in an objective manner. Furthermore, unlike argumentative writing , an expository paper mustn’t contain personal takes and justifications on the topic.

Its Purpose

The purpose of expository essay writing is to present some information to the reader in a clear and objective way. As brought up above, expository essays shouldn’t contain personal viewpoints on the topic. Here, the writer’s job is to do factual analysis, find the most reliable sources, and include them in the essay.

When practicing expository essay writing, you want to detach from providing your view and include authoritative thoughts on the subject only. Otherwise, you risk writing an opinionated piece that doesn’t fall into the category of expository writing. 

The verb “expose” here conveys the idea behind this essay very clearly with some of its meanings : “to bring to public notice; disclose; reveal; to introduce (to) or acquaint (with).”

Topic Examples

Since expository essay prompts don’t require students to present an opinion or a stance, topics often include sufficient information one can find on the Internet. If your assignment sheet calls for taking a position and justifying it, you have probably been assigned a different essay—argumentative, for instance. 

Be that as it may, should your instructor allow you to come up with the topic, ensure to write a prompt that doesn’t require arguing, refuting, or taking any step that involves voicing your position. To help you with that undertaking, take a look at the following expository writing ideas:

• Explain how the eating habits of American people have changed within the last 50 years.
• Illustrate the development of machine learning.
• Discuss the three most negative outcomes of racism.
• Why do locals of the most prominent tourist destinations dislike the vast majority of tourists?
• Describe the process of building a house.
• The apparent influence of a particular philosopher: What fields have been changed thanks to them?
• Provide three crucial steps to building self-esteem.
• Explain what cancel culture is and how it can affect our society.
• Compare healthcare in the United States and Australia and find their differences and similarities.
• Show causality between junk food and health issues.

6 Main Expository Paper Types

Although having a typical structure (the following section will elaborate on this point), an expository essay is a broad class of writing that has different types that narrow down the paper’s purpose. Below are the six core types of an expository essay. Getting familiar with them will help you decide on your writing strategy. 

1. Descriptive essay – Choosing this type, you need to gather and provide details regarding a situation, event, object, time frame, and so on. This essay requires being as clear and concise as possible, following an academic writing style, and taking neutrality in judging.

2. Definition essay – Some words or concepts may be hard to understand right away. This expository essay variety strives to collect the necessary data, process it, and provide coherent, comprehensive, and accurate information on the subject, defining it in detail.

3. Process essay – A process (how-to) paper shows how something is done from the ground up. This often serves as a step-by-step manual for those who want to know how to do a specific thing—a recipe, for instance—but aren’t aware of the required steps. 

4. Cause and effect essay – In a cause and effect essay, you typically investigate the causality between objects or events. For example, you can explore the cause for a specific decree issued and the effects—both short and long-term—it has already brought and can bring in the future.

5. Problem and solution essay – In a problem-solution essay, you pick a problem—be it related to a social, economic, political, or environmental aspect—and try to find the most effective solutions. Again, you must provide explanations from credible sources.

6. Compare and contrast essay – In compare and contrast writing, you choose two subjects and aim to find how exactly they are different and what similarities they share, if any. Comparing tax laws of two states would be a good example of expository writing of this subtype.

Structure of Expository Essays

When it comes to an expository essay structure or format , it is pretty straightforward. No matter the type you choose to follow, remember that the three main parts of an expository essay are an introduction, body, and conclusion. These are the building blocks of every essay, with their unique functions and aims.

Certainly, it is your instructor who assigns the task. They can customize it, asking you to hit a particular word count, follow a specific citation style, and even include a different number of paragraphs, not the standard five. 

However, if your instructions don’t state the number of sections your paper needs to meet, follow the standard essay writing process ; a typical expository essay would have five paragraphs: one intro, three body paragraphs, and one for the ending.

Format Template

Writing an expository essay requires a thoughtful approach. The latter isn’t easy to accomplish, as you need to find sources, identify the paper type you want or need to follow, and develop a thesis statement. However, a template can simplify your writing process. 

Open Template

This format template is a helpful and practical tool that allows you to preserve a series of logical, objective, and accurate statements, thus designing a good expository essay. Moreover, such a layout speeds up the entire writing process and wards off any additional information you might think of including when creating the first draft.

Outline Example

Building an outline is a rather simple activity, mainly if you aren’t requested to attach it alongside your expository essay. You can create an outline unique in format and structure but ensure it is meaningful to your writing session, i.e., it points you in the right direction, helps you work more productively, and eliminates any confusion.

With that in mind, please take a look at the following expository essay outline example to get a grasp of what your five-paragraph essay could look like.

Topic : Foucauldian principle of governmentality

• Governmentality: Definition and foundations.
• Thesis statement: Governmentality is a pivotal element of governing subjects—people—in various ways and from various places, such as schools, households, and other organizations.
• A school as a governing utility.
• A household as an element to shape the conduct of people.
• An organization as an instrument to affect people and their behavior.
• The concept of governmentality is crucial and goes way beyond government institutions.
• The reinforcement of key points from the body paragraphs and explanation of the effects academia, family, and other organizations (profit, non-profit, NGOs, etc.) have on people’s conduct.
• Repercussions of governmentality and its implications these days and in the future.

How to Write an Expository Essay (in 7 Steps)

Now that you’re aware of what an expository essay is, the purpose it carries, and the types and parts it has, let’s move forward and try to answer how to write it. There is no universal strategy regarding writing an expository essay. What one finds effective might not prove the same for another. 

There are, indeed, elements that often intertwine in various writing approaches, like brainstorming, researching, and thesis writing. These are the three focal things you must do above all else. Other parts can be drafted in any order. Notwithstanding, here are seven steps that will enable you to create a decent expository essay.

1. Brainstorming

Generating thoughts is part and parcel of any essay. Brainstorming allows you to revise what you know about the topic and narrow your focus to several aspects you want to write about. Fortunately, you can employ various brainstorming techniques , such as listing, clustering, freewriting, and rapid ideation–to name a few–and decide which one works for you the best.

2. Researching

Demanding and time-consuming as it might often seem, researching is essential before delving into writing. Not only does it help you locate the necessary sources and include them in your paper, but research also enriches your expertise and makes you more competent on the subject matter. The most efficient, trusted, and easiest way to carry out research is to visit pages like Google Scholar, ResearchGate, Academia.edu, and alike.

A thesis statement is a constitutive part of every paper. A good thesis helps the writer address the issue and work around it, finding solutions or successfully executing any other purpose the essay strives to achieve. By default, a thesis appears in the introductory paragraph. You can build a thesis in various ways depending on the paper type you choose to follow. Nonetheless, ensure it has a clear claim and supporting details. 

4. Introduction

The introduction’s primary goal is to provide some fundamentals on the topic (to make the audience more cognizant of what your paper is about), explain the essence of the field, and focus on aspects you present in the thesis. You are encouraged to create a gripping opening to catch the readers’ attention and ensure they’re interested in learning more. It can be a quote, exciting and relevant fact, or a rhetorical question.

Note: To learn more about essay introductions, please check this guide: How to Start an Essay

While the introductory paragraph starts broad and aims to prepare the audience for the topic, the body part is where your focus shrinks. These (typically) three paragraphs work on your thesis statement, attempting to develop it as profoundly as possible. Regardless of your expository essay type, each of the three paragraphs must comprise five components: a topic sentence, supporting evidence, examination, encapsulation, and transition to the following paragraph.

6. Conclusion

In the final section, your task is to restate your thesis statement and include essential information you’ve provided within the entire paper. While the conclusion predominantly does that, you can also highlight the topic’s development throughout the years and the necessity to investigate the venue. It will help you end on a high note and call for action, for example, start a discussion.

Note: To find out more details regarding conclusions, we invite you to read this guide: How to End an Essay

7. Revision

The editing process is equally demanding and requires a practical attitude. Once you write the draft, take a break and step away from the piece. Then return to an expository essay and start making one step at a time, checking the paper’s structure, citation style, wording, and content. Importantly, pay close attention to a thesis statement and ensure it clearly corresponds with every topic sentence.

Final Tips and Takeaways

As mentioned earlier, expository essay writing focuses on doing adequate research and completing the main goal set by the key verb ( explain, discuss, provide, compare , etc.) It would be reasonable to re-emphasize the chief feature of an expository essay. Whatever type of essay an assignment requires you to follow, limiting your engagement in the topic is crucial. Failing to do that will result in you writing an argumentative paper with a completely different purpose.

Also, keep in mind that six types of expository essays exist: descriptive, definition, process, cause-and-effect, problem and solution, and compare and contrast. Although they all lean on one structure (introduction, body, conclusion), they are different in presenting the content, so ensure you choose the right type for your subject.

Composing an outline is the best way to remain focused and productive, especially when writing an expository paper.

Below is a list of additional tips to write an expository essay. Incorporating them with the recommendations from the above will let you write a sound expository essay:

• Double-check facts : Since you fully bank on sources, make sure they are widely accepted, updated, and authoritative.
• Watch your tone: Even if you don’t use personal pronouns, your tone may be too forceful and may create an impression that you try to impose an opinion.
• Keep your thesis in mind: Many forget about a thesis once they write it. Ensure you remember your thesis statement during the whole writing process.

When writing a persuasive paper , the writer aims to convince the receiver. In turn, an expository essay gravitates toward neutrality, making the writer rely on facts and present already established opinions, describe processes, explain notions, etc.

As a rule, students should refrain from using first-person pronouns in their papers, which includes expository essays. But of course, there might be changes, which is why it’s imperative to familiarize yourself with the assignment’s requirements before you get started. Writing an expository essay in the first person is possible only if your educator allows you to do so. 

If you’ve been assigned a typical expository essay, there are several things you should avoid at all costs, with the first-person pronouns being the first one. Besides that, don’t include informal language; people come from different cultural backgrounds, so what one group finds acceptable might be offensive to another. Finally, learn your word limit and estimate how much info you can include in the paper.

What Is An Expository Essay?

An expository essay is one which is used to explain something, in the most simple terms. The word expository comes from the word expose, and this means to uncover something so that other people are able to understand it for what it is. This type of essay is therefore used as a way of explaining or clarifying the subject for the reader.

It might function as an evaluation or an investigation, but it could also function as an argument surrounding the idea for clarification. It is easy to confuse this type of essay with the argumentative essay but the key difference is that the expository essay will remain neutral whereas the argumentative essay tends to take a side.

A good expository essay will allow the reader to gain a certain level of knowledge on the subject that is being explained and will clear up any misunderstandings that the reader may have had. The essay serves as a way of looking neutrally at any given topic and does not give the writers personal views.

Let’s take a look at some examples of topics you might write on.

• Explain Religion and which one you should introduce your child to.
• Explain Global warming.
• Explain Science and its effect on the world.
• Explain the best countries to visit for families/singles/couples
• Explain what life is like for an illegal immigrant
• Explain how music has an influence on our way of life
• Explain the best time period of the last 500 years.
• Write an essay on a certain sport.
• Explain why parents need to be strict with their children.
• Explain cryptocurrency and how it has affected the economy.
• Explain why your admire someone.

Research The Topic

Once you have selected your topic, it is important that you perform the relevant research. When writing an essay, it is critical that you present data and facts that are up to date and correct. This means that research should be an integral part of your preparations in writing an expository essay.

Choose Some Examples

In order to properly explain the topic, you should present your readers with some examples and choosing the right ones will not only keep your reader engaged but will also serve to explain the topic in the most detailed and easy to understand way. For example, if you have decided to write about which religion you should introduce your children to, you might select one or two of the major religions which you believe to the most relevant, for example Islam and Christianity.

Outline Your Essay

Every essay needs a good essay outline in order for the author to be able to write the piece effectively. Creating your essay outline is one of the most integral parts of the process and good attention should be paid to it.

• Introduction – In your introduction, you should include a hook to get the attention of the reader and a short description of what the essay is going to be about. You should also include your thesis statement which will tell the reader the purpose of the essay.
• Body paragraphs – usually an essay will be made up of three body paragraphs, however you can be flexible with this should you need more or less words to complete your work. In each of these paragraphs you should include one argument point along with any data and sources to back this up.
• Conclusion – The conclusion will wrap up all the ideas that were talked about during the essay and will refer back to the thesis statement once again.

Write Your Essay

Remember that the purpose of an expository essay is to clarify something to the reader and so it is important that you write in clear terms which are easy to understand.

You should include any examples of the topic which are backed up by data and statistics as this will give the reader a greater knowledge on the subject by the end of the essay.

Once you have finished writing, it is very important to go back over your work and check for any spelling errors or grammar mistakes as well as adding and taking away any necessary information.

An Example Of An Expository Essay

As a way to gain a further understanding on what an expository essay should look like and how it should be written, we are now going to take a look at a passage taken from an expository essay called ‘Learning to read’ written by Malcolm X .

It is because of my letters I happened to come across beginning to acquire a form of homemade education.

I was becoming more and more frustrated in not being able to say what I had wanted to convey in a letter, particularly ones which were written to Mr E Muhammad.

On the street, I’d been the hustler who was most articulate and has commanded everyone’s attention when I had said something. However, now whilst attempting to write in simple English, not only was I not articulate but I was not even functional. What would I sound like if I wrote in slang, a way I would normally  say  it, something along the lines of ‘Hey daddy, lemme pull ya coat about the cat’

Many of the people who hear me today either in person or on the television, perhaps who read something said by me, assume that I went to school for much longer than just the 8th grade. This is an impression given entirely because of my prison studies.

If you search the Internet for a definition of an expository essay , you might become confused. Some books and websites define them as "how to" essays, while others give a long and confusing definition that seems to include every possible essay type out there.

Expository essays are simply essays that explain something with facts, as opposed to using opinion to inform the reader. Sample styles for expository essays may include:

• Papers that described how to do something ( how to essay ).
• Papers that analyze events, ideas, objects, or written works.
• Papers that describe a process ( step by step essay) .
• Papers that explain/describe a historical event ( descriptive essay ).

Expository essays are often written in response to a prompt that asks the writer to expose or explain a specific topic. Essay questions on tests are normally written to prompt an essay in this very style, and may look like the following:

• Explain the events leading up to the Revolutionary War.
• Explain how to balance a checkbook.
• Describe the composition and function of a chicken's egg.
• Explain the process of changing a tire.

An expository essay should have the same basic structure as any typical essay , with an introductory paragraph , body paragraphs , and a summary or conclusion. The length of your essay can vary, according to context.

The introductory paragraph will contain the thesis sentence , and the topic of the thesis should be grounded in fact.

A concluding essay will provide a summary of your main points and re-statement of your goal or thesis.

An expository essay attempts to explain a topic in-depth, demonstrating expert knowledge and understanding.

This form of essay is structured around the clear, factual presentation of information, devoid of the writer’s personal opinions or arguments.

The primary goal is to inform or explain rather than persuade.

Unlike an argumentative essay, which is built around defending a particular point of view with evidence and persuasion, an expository essay maintains a neutral stance, focusing on delivering straightforward facts and explanations.

An example of expository writing could be an article explaining the process of photosynthesis.

The article would systematically describe each stage of how plants convert sunlight into energy, detailing the role of sunlight, water, and carbon dioxide.

It would explain the sequence of reactions – first, second, third, fourth, fifth – that occur and the importance of each step in supporting the life of the plant.

An expository essay generally follows this essay format:

• A) To persuade the reader to adopt a particular viewpoint
• B) To inform or explain a topic clearly
• C) To present the writer’s personal opinions and arguments
• D) To entertain the reader with creative writing
• A) An expository essay uses creative storytelling techniques
• B) An expository essay remains neutral and avoids personal opinions
• C) An expository essay focuses on persuading the reader with evidence
• D) An expository essay prioritizes the writer’s personal experiences

Differences Between Expository and Argumentative Essays

Expository and argumentative essays are both common writing styles in academic and professional contexts, but they serve different purposes and follow different structures.

Here are the key differences between them:

• Expository Essay : The primary purpose is to explain, describe, or inform about a topic. It focuses on clarifying a subject or process, providing understanding and insight.
• Argumentative Essay : The goal is to persuade the reader to accept a particular point of view or to take a specific action. It’s about presenting a stance and supporting it with evidence and logic.
• Expository Essay : It maintains a neutral and objective tone. The writer presents information factually and impartially, without expressing personal opinions or biases.
• Argumentative Essay : It often adopts a more assertive, persuasive, and subjective tone. The writer takes a clear position and argues in favor of it, using persuasive language.
• Expository Essay : The reader is expected to gain knowledge, understand a process, or become informed about a topic. There’s no expectation for the reader to agree or disagree.
• Argumentative Essay : The reader is encouraged to consider the writer’s viewpoint, evaluate arguments, and possibly be persuaded to adopt a new perspective or take action.

Expository Essay – In a Nutshell

An expository essay aims to provide a solution or explanation of a subject or issue at hand. Techniques in writing this type of essay can come in handy when a fact-based analysis is required in any field. Learn everything you need to know about writing an expository essay in this article:

• There are 4 types of expository essays: Descriptive essay, process essay , compare and contrast essay , and cause and effect essay .
• An expository essay includes 3 main sections : Introduction, body, and conclusion.
• Learn tips and tricks to consider when writing an expository essay

Definition: Expository essay

A style of academic writing known as an expository essay tries to clarify, observe, and describe a thought, problem, or notion. It entails looking into a theory, assessing the supporting data, outlining the theory, and then developing an argument based on the research.

Expository essays follow a format similar to other types of academic essays , such as persuasive essays or argumentative essays . The primary distinction is that the expository essay necessitates more investigation and factual information to substantiate the claim. Common examples of expository essays include a process, or how-to essay that provides instructions on how to accomplish a task, assembly instructions, and newspaper articles.

The purpose of an expository essay

An expository essay is written when the researcher intents to provide a solution or an explanation about a specific topic or issue. The primary purpose of such an essay is to explain or analyze a complex topic and is often used to explore complex or controversial issues. Mostly, these essays investigate an idea or subject, evaluate the evidence available, develop the idea, and provide an argument regarding that idea clearly and concisely.

Types of expository essays

There are four main types of expository essays:

Descriptive essay

A descriptive essay gives details on a particular person, place, thing, or experience. The author describes the topic with sensory information describing an individual, place, thing, or experience while giving in-depth information about the subject. Providing an intricate description of something or an event is the primary objective of such an essay.

Process essay

A process essay describes how to carry out a task or how something is supposed to take place. The author must ensure that the steps in the process are described in chronological order. A process essay’s primary goal is to give comprehensive directions on carrying out a task with minimal mistakes.

A beach description essay can discuss the sound of the waves lapping against the shore, the salty air, and the sensation of sand between the toes. Additionally, a person’s physical attributes, psychological traits, and interests could all be discussed in a descriptive essay about that individual.

A process essay on how to bake a cake might describe the processes involved, from combining the ingredients to placing the cake in the oven. Also, planting crops must follow a specific process lest they fail in their tracks.

Compare and contrast essay

A compare and contrast essay explains the differences and similarities between two or more individuals, things, places, or experiences. In a comparison essay, two objects are compared, and their similarities and differences are discussed. This essay’s primary goal is to make the reader understand the subjects under comparison.

Cause and effect

A cause and effect essay explains the reasons for something or the effects of something. This essay will discuss the causes of a problem or situation and its consequences. The main purpose of a cause-and-effect essay is to help the reader understand the reason behind a problem or situation.

In a compare and contrast essay about two nations, you might talk about how the two nations’ cultures, languages, and religions differ. Further, a compare and contrast essay on two books can discuss how the themes are similar but the character development differs.

An essay on obesity’s causes and effects can go over the factors contributing to the country’s rising obesity rates. Also, a cause and effect essay about the Vietnam War can go into the conflict’s origins and how it affected the Vietnamese people

Structuring an expository essay

The structure of this essay is similar to that of other essays, such as the five-paragraph essay.

The introduction:

Introduces the essay’s core idea while providing critical background information. Start your introduction with a catchy sentence to draw the reader in, such as rhetorical questions, quotations, anecdotes, concessions, intriguing facts, or questions that will be addressed in your body section. The thesis statement for a narrative essay has a slightly different function than an expository essay because the former can introduce the plot’s events.

A three-paragraph body is the standard format for such essays. The topic is introduced in the first paragraph, followed by complementary information in the second paragraph, and then the bottom-line section as the third body paragraph.

The conclusion:

An expository essay also has a conclusion, acting as the summary of the essay’s main points.

How to write an expository essay

The most efficient method to begin an essay is simply, to begin writing. Get your ideas down on paper first without worrying about grammar or spelling. Check it for grammatical and spelling issues when you’ve finished writing your essay.

Make sure your thoughts are concise, and your essay flows naturally while editing. Read your writing aloud as a means to verify this. If you become lost or confused while reading your work, this is a good indicator that you have probably not adequately ordered your work.

What is the Sahm Rule?

How the sahm rule works, types of sahm rule indicators, history of the sahm rule, limitations of the sahm rule, the bottom line, the sahm rule recession indicator definition and how it's calculated.

Erika Rasure is globally-recognized as a leading consumer economics subject matter expert, researcher, and educator. She is a financial therapist and transformational coach, with a special interest in helping women learn how to invest.

The "Sahm Rule" is a recession indicator created and named after Claudia Sahm, a macroeconomist who worked at the Federal Reserve and the White House Council of Economic Advisers. According to the Sahm Rule, the early stages of a recession is signaled when the three-month moving average of the U.S. unemployment rate is half a percentage point or more above the lowest three-month moving average unemployment rate over the previous 12 months.

The Sahm Rule has been widely recognized for its accuracy, simplicity, and ability to quickly reflect the onset of a recession.

Key Takeaways

• The Sahm Rule is a indicator that looks at signals related to the onset of a recession.
• According to the rule, the early stages of recession are signaled when the three-month average unemployment rate moves above the lowest three-month moving average unemployment rate over the last 12 months by half a percentage point or more.
• The rule has become widely recognized as a recession indicator due to its accuracy and simplicity.
• The Sahm rule was first introduced by macroeconomist Claudia Sahm in 2019 as part of a policy proposal.

The unemployment rate represents the percentage of the overall labor force that is unemployed. The rate tends to rise when the economy is struggling and workers are having difficulty finding jobs, and fall when the economy is strong and workers can more easily find jobs. The Bureau of Labor Statistics (BLS) typically releases the unemployment rate for the previous month on the first Friday of every month. The unemployment rate is one of the main economic indicators used to measure the health of the economy, and the Sahm Rule inputs the rate into a simple formula to determine whether the U.S. is headed into a recession.

The rule compares the value of the current three-month moving average unemployment rate to the value of the lowest three-month moving average unemployment rate over the last 12 months. If the former is half a percentage point or more above the latter, the Sahm Rule indicates that U.S. is in the early stages of a recession. The Sahm Rule uses the three-month moving average unemployment rate—rather than the current unemployment rate—to prevent overreacting to a single month of data, Sahm said as a guest on The Investopedia Express podcast released in April 2024.

The Sahm Rule simply indicates that the economy is in the early stages of a recession. Since the early 1970s, the indicator has never been triggered outside of a recession, according to Sahm. Historically, when the unemployment rate passes the threshold outlined by the Sahm rule, it continues to increase.

The Federal Reserve Economic Data (FRED) database includes current and real-time Sahm Rule recession indicators.

Current Sahm Rule Recession Indicator

The BLS regularly revises the unemployment rate of previous months based on additional information from its survey that was not initially available. The current Sahm Rule recession indicator is calculated using the unemployment rate's revised values.

Real-Time Sahm Rule Recession Indicator

Unlike the current Sahm Rule recession indicator, the real-time Sahm Rule recession indicator uses "real-time" data. It is calculated using just the unemployment rate and recent history of unemployment rates that were available in a given month.

Sahm first introduced the indicator that would later be named after her as part of a policy proposal called "Direct Stimulus Payments to Individuals" published by The Hamilton Project, an economic policy initiative that is part of the Brookings Institution. The proposal was also included in The Hamilton Project's book "Recession Ready: Fiscal Policies to Stabilize the American Economy" published in 2019.

In the proposal, Sahm explained that consumer spending tends to slow significantly during recession growth, which can make job losses (and a recession overall) worse. She proposed that to combat that unemployment, the government distribute stimulus payments automatically to families in the face of a recessions—specifically, when the three-month average national employment rate jumps at least half a percentage point relative to its low over the last 12 months.

"Recent research finds that broadly distributed, lump-sum payments to individuals directly boost spending and help stabilize demand, making these types of payments effective responses to recessions," Sahm explained. "The total amount of stimulus would offset about half of the slowdown in consumer spending, totaling about 0.7 percent of GDP." Gross domestic product (GDP) refers to a country's total market value of goods and services within a certain time frame. Fiscal policies like the one Sahm proposed are known as automatic stabilizers .

The indicator became widely recognized, with the Federal Reserve adding it to the FRED database in October 2019.

As Sahm has pointed out in her newsletter, the rule is "empirical regularity," not a proposition. She emphasized that this means that the rule can also be broken.

For example, Sahm wrote in an April 2022 newsletter, imagine a scenario in which the unemployment rate increased hovered around 3.5%, up from a low of 3.0%, meeting the criteria for signaling the early stages of a recession based on the Sahm Rule. However, if around that same time, GDP growth held around 2.5%, down from a high of 5.5%, and inflation gradually slid down to 2%, such a combination of circumstances probably wouldn't constitute a recession, she explained.

What is the Sahm Rule today?

First introduced in 2019, the Sahm Rule is a recession indicator based on conditions of the labor market. When the three-month average unemployment rate rises above its 12-month low by at least half a percentage point, we are in the early stages of a recession, according to the rule.

Who created the Sahm Rule?

Claudia Sahm, a macroeconomist who worked at the Federal Reserve and the White House Council of Economic Advisers, introduced the indicator as part of a policy proposal. The rule was then named after her.

How Accurate is the Sahm Rule?

The rule has proved to be very accurate with the indicator always triggering in the early stages of a recession and never outside of one since the 1970s.

The Sahm Rule refers to an indicator that signals the early stages of a recession. According to the rule, the beginning of a recession is signaled when the three-month moving average unemployment rate is half a percentage point or more higher than the lowest three-month moving average unemployment rate over the last 12 months. Historically, when the unemployment rate has passed this threshold, it has continued to rise.

What Is Developmental Psychology?

Conditions treated, training and certifications.

Developmental psychology is the study of how humans grow, change, and adapt across the course of their lives. Developmental psychologists research the stages of physical, emotional, social, and intellectual development from the prenatal stage through infancy, childhood, adolescence, and adulthood.

This article covers developmental psychology, including the definition, types, life stages, and how to seek treatment when necessary.

Defining Developmental Psychology

According to the American Psychological Association (APA), developmental psychology is a branch of psychology that focuses on how human beings grow, change, adapt, and mature across various life stages. Developmental psychology is also known as human development or lifespan psychology.

In each of the life stages of developmental psychology, people generally meet certain physical, emotional, and social milestones. These are the major life stages, according to developmental psychologists:

• Prenatal development: Developmental psychologists are interested in diagnoses, such as Down syndrome, that might be noticed during the prenatal (before birth) stage. They also investigate how maternal behaviors (behaviors of the pregnant parent), such as nutrition and drug use, could affect the developing fetus.
• Early childhood: Developmental psychologists are interested in whether young children are meeting key milestones, such as walking, talking, and developing fine motor skills (coordination in the hands, fingers, and wrists). They might also be interested in a child’s attachment to their parents and other caregivers.
• Middle childhood: In this stage, children learn about the world and acquire knowledge through experimentation, questioning, and observation. They begin to develop logical and moral reasoning skills.
• Adolescence: Adolescence is a time of major strides in terms of personal development and identity formation. Teens and young adults might experiment with various identities, career choices, or areas of interest.
• Early adulthood: During early adulthood, most people are focused on preparing for the rest of their lives through a focus on education, career, and financial independence. Romantic relationships, marriage, family-building, setting down “roots,” and child-rearing are often a focus of this life stage.
• Middle adulthood: Middle-aged adults are often focused on helping the next generation, whether in their own family or their community. They are also often interested in the legacy they’ll leave behind.
• Older adulthood: In addition to physical health challenges, older people might face issues like dementia or cognitive decline (decline in thinking, remembering, and reasoning). Older adults also often need to reflect on their lives, tell their stories, and find meaning and peace within the aging process.

The Origins of Developmental Psychology

During its early development as a branch of psychology in the late 19th and early 20th centuries, developmental psychology focused on infant and child development. As the field grew, so did its focus. Today, developmental psychologists focus on all stages of the human lifespan.  

Theories of Developmental Psychology

As developmental psychology grew over time, various researchers proposed theories about how to understand the process of human development. Depending on their training, a developmental psychologist might focus on a specific theory or approach within the field. 

These are a few of the major branches of developmental psychology.

Psychosocial Developmental Theory

Building on Austrian neurologist and founder of psychoanalysis Sigmund Freud’s theory of psychosexual development , psychologist Erik Erikson proposed a lifespan theory that included eight stages of psychosocial development .

Each of the stages corresponds to both an age range and a core “crisis” (such as trust vs. mistrust in infancy) that must be resolved before someone can move on to the next.

Cognitive Developmental Theory

Swiss psychologist Jean Piaget’s theory of cognitive development focuses on how children and youth gradually become able to think logically and scientifically. Piaget proposed that cognition develops through four distinct stages of intellectual development, beginning at birth and ending at age 12.

Attachment Theory

Attachment theory , originally developed by psychoanalyst John Bowlby, establishes the importance of a supportive, steady, and loving caregiver in infant and child development. If a child doesn’t establish such a connection, or if they experience parental separation or loss, they might continue to struggle with healthy attachments as they get older.

Sociocultural Developmental Theory

While Bowlby considered the importance of the immediate family in child development, psychologist Lev Vygotsky’s sociocultural developmental theory looks at the role of society. Cultural influences and beliefs can have a profound impact on how a person views their own identity and relates to others.

Developmental psychologists can help people address developmental issues in order to reach their full potential. 

Some of the conditions a developmental psychologist might treat include:

• Learning disabilities
• Intellectual disabilities
• Developmental delays
• Motor skill delays
• Issues with social and emotional development
• Auditory processing (hearing) disorder
• Autism spectrum disorder (ASD)
• Speech and language delays
• Mental health conditions like anxiety and depression, especially related to life stages

The training required to become a developmental psychologist is similar to that in other subfields of psychology. Most developmental psychologists start with an undergraduate degree in psychology or a related field, followed by a master’s degree and a doctoral degree (PhD). 

There are many master’s, graduate certificate, and PhD programs in developmental psychology in the United States. Some focus on a certain part of a person's lifespan, such as child and adolescent development. In addition to research and teaching, graduates may participate in a practicum or internship to pursue licensing as a therapist. 

When to Seek Treatment

If you're concerned that your child is facing a developmental delay, a developmental psychologist can assess them to ensure that they are meeting their milestones. It's best to seek an assessment, diagnosis, and treatment early, so intervention can begin as soon as possible.

Examples of when to see a developmental psychologist may include:

• An infant is struggling to bond with their parents.
• A toddler is missing milestones, such as walking or developing speech.
• A school-aged child is not progressing appropriately in reading or writing.
• An adolescent is facing challenges related to social and/or emotional development.

A developmental psychologist might perform physical and/or cognitive testing to diagnose your child or refer them to another specialist, including the following:

• Physical therapist (helps people improve movement and manage pain)
• Occupational therapist (helps people adjust to everyday activities after injury, illness, or disability)
• Speech-language pathologist (treats speech, language, and social and cognitive communication)
• Psychotherapist (uses talk therapy to treat mental health conditions)
• Neurologist (medical doctor who treats disorders of the brain, spinal cord, and nerves)
• Psychiatrist (medical doctor specializing in mental health conditions)

A developmental psychologist will also likely ask you and your child questions about issues in areas of their life such as friends, behavior, or school performance.

In addition to working with infants and children, developmental psychologists can also help people at any stage of life. In particular, many older adults benefit from working with a developmental psychologist if they're experiencing symptoms of dementia, ill health, or cognitive decline.

Developmental psychology is the study of how human beings grow and change throughout their lives. Many developmental psychologists focus on the intellectual, social, emotional, and physical development of infants, children, and adolescents. Others treat and assess people of all ages. 

Developmental psychologists can treat issues such as developmental delays, intellectual disabilities, learning disabilities, speech and language delays, motor skill delays, dementia, anxiety, depression, auditory processing disorder, autism spectrum disorder, and more. They also make referrals to other specialists, such as physical therapists, psychiatrists, and speech-language pathologists.
