Informative Essay — Purpose, Structure, and Examples

What is informative writing?

Informative writing educates the reader about a certain topic. An informative essay may explain new information, describe a process, or clarify a concept. The provided information is objective, meaning the writing focuses on presentation of fact and should not contain personal opinion or bias.

Informative writing includes description, process, cause and effect, comparison, and problems and possible solutions:

Describes a person, place, thing, or event using descriptive language that appeals to readers’ senses

Explains the process to do something or how something was created

Discusses the relationship between two things, determining how one ( cause ) leads to the other ( effect ); the effect needs to be based on fact and not an assumption

Identifies the similarities and differences between two things; does not indicate that one is better than the other

Details a problem and presents various possible solutions ; the writer does not suggest one solution is more effective than the others

Purpose of informative writing

The purpose of an informative essay depends upon the writer’s motivation, but may be to share new information, describe a process, clarify a concept, explain why or how, or detail a topic’s intricacies.

Informative essays may introduce readers to new information .

Summarizing a scientific/technological study

Outlining the various aspects of a religion

Providing information on a historical period

Describe a process or give step-by-step details of a procedure.

How to write an informative essay

Regardless of the type of information, the informative essay structure typically consists of an introduction, body, and conclusion.

Introduction

Background information

Explanation of evidence

Restated thesis

Review of main ideas

Closing statement

Informative essay introduction

When composing the introductory paragraph(s) of an informative paper, include a hook, introduce the topic, provide background information, and develop a good thesis statement.

If the hook or introduction creates interest in the first paragraph, it will draw the readers’ attention and make them more receptive to the essay writer's ideas. Some of the most common techniques to accomplish this include the following:

Emphasize the topic’s importance by explaining the current interest in the topic or by indicating that the subject is influential.

Use pertinent statistics to give the paper an air of authority.

A surprising statement can be shocking; sometimes it is disgusting; sometimes it is joyful; sometimes it is surprising because of who said it.

An interesting incident or anecdote can act as a teaser to lure the reader into the remainder of the essay. Be sure that the device is appropriate for the informative essay topic and focus on what is to follow.

Directly introduce the topic of the essay.

Provide the reader with the background information necessary to understand the topic. Don’t repeat this information in the body of the essay; it should help the reader understand what follows.

Identify the overall purpose of the essay with the thesis (purpose statement). Writers can also include their support directly in the thesis, which outlines the structure of the essay for the reader.

Informative essay body paragraphs

Each body paragraph should contain a topic sentence, evidence, explanation of evidence, and a transition sentence.

A good topic sentence should identify what information the reader should expect in the paragraph and how it connects to the main purpose identified in the thesis.

Provide evidence that details the main point of the paragraph. This includes paraphrasing, summarizing, and directly quoting facts, statistics, and statements.

Explain how the evidence connects to the main purpose of the essay.

Place transitions at the end of each body paragraph, except the last. There is no need to transition from the last support to the conclusion. A transition should accomplish three goals:

Tell the reader where you were (current support)

Tell the reader where you are going (next support)

Relate the paper’s purpose

Informative essay conclusion

Incorporate a rephrased thesis, summary, and closing statement into the conclusion of an informative essay.

Rephrase the purpose of the essay. Do not just repeat the purpose statement from the thesis.

Summarize the main idea found in each body paragraph by rephrasing each topic sentence.

End with a clincher or closing statement that helps readers answer the question “so what?” What should the reader take away from the information provided in the essay? Why should they care about the topic?

Informative essay example

The following example illustrates a good informative essay format:

Writing an Informative Essay

Informative essays engage readers with new, interesting, and often surprising facts and details about a subject. Informative essays are educational; readers expect to learn something new from them. In fact, much of the reading and writing done in college and the workplace is informative. From textbooks to reports to tutorials like this one, informative writing imparts important and useful information about a topic.

This tutorial refers to the sample informative outline and final essay written by fictional student Paige Turner.

Reasons to Write Informatively

Your purpose for writing and the audience for whom you are writing will impact the depth and breadth of information you provide, but all informative writing aims to present a subject without opinions or bias. Some common reasons to write informatively are to

• report findings that an audience would find interesting,
• present facts that an audience would find useful, and
• communicate information about a person, place, event, issue, or change that would improve an audience’s understanding.

Characteristics of Informative Essays

Informative essays present factual information and do not attempt to sway readers’ opinions about it. Other types of academic and workplace writing do try to influence readers’ opinions:

• Expository essays aim to expose a truth about an issue in order to influence how readers view the issue.
• Persuasive essays aim to influence readers’ opinions, so they will adopt a particular position or take a certain course of action.

Expository and persuasive essays make “arguments.” The only argument an informative essay makes is that something exists, did exist, is happening, or has happened, and the point of the essay is not to convince readers of this but to tell them about it.

• Informative essays seek to enlighten and educate readers, so they can make their own educated opinions and decisions about what to think and how to act.

Strategies for Writing Informatively

Informative essays provide useful information such as facts, examples, and evidence from research in order to help readers understand a topic or see it more clearly. While informative writing does not aim to appeal emotionally to readers in order to change their opinions or behaviors, informative writing should still be engaging to read. Factual information is not necessarily dry or boring. Sometimes facts can be more alarming than fiction!

Writers use various strategies to engage and educate readers. Some strategies include

• introducing the topic with an alarming fact or arresting image;
• asserting what is true or so about the subject in a clear thesis statement;
• organizing the paragraphs logically by grouping related information;
• unifying each paragraph with a topic sentence and controlling idea;
• developing cohesive paragraphs with transition sentences;
• using precise language and terminology appropriate for the topic, purpose, and audience; and
• concluding with a final idea or example that captures the essay’s purpose and leaves a lasting impression.

Five Steps for Getting Started

1. Brainstorm and choose a topic.

• Sample topic : The opioid epidemic in the United States.
• The opiod epidemic or even opiod addiction would would be considered too broad for a single essay, so the next steps aim to narrow this topic down.

2. Next, write a question about the topic that you would like to answer through research.

• Sample question : What major events caused the opioid crisis in the United States?
• This question aims to narrow the topic down to causes of the epidemic in the US.

3. Now go to the Purdue Global Library to find the answers to your research question.

As you begin reading and collecting sources, write down the themes that emerge as common answers. Later, in step four, use the most common answers (or the ones you are most interested in writing and discussing) to construct a thesis statement.

• Sample answers: aggressive marketing, loopholes in prescription drug provider programs, and economic downturn.

4. Next, provide purpose to your paper by creating a thesis statement.

The thesis attempts to frame your research question. The sample thesis below incorporates three of the more common answers for the research question from step two: What caused the opioid crisis in the United States?

• Thesis Statement : Aggressive marketing, loopholes in prescription drug provider programs, and economic downturn contributed to the current opioid crisis in the United States.
• Writing Tip : For additional help with thesis statements, please visit our Writing a Thesis Statement article. For help with writing in 3rd person, see our article on Formal Vs. Informal Writing .

5. Now follow each numbered step in the “Suggested Outline Format and Sample” below.

Sample answers have been provided for “I. Introduction” and “II. First Cause.” A complete sample outline can be seen here. A complete sample informative essay can be seen here.

I. INTRODUCTION

A. First provide a topic sentence that introduces the main topic: Sample topic sentence : There is a current prescription pain medication addiction and abuse epidemic possibly caused by an excessive over prescription of these medications.

C. Sample sentence two with evidence to support the main topic : Volkow indicated “more than 300,000 Americans have died of an opioid overdose” since 2013 (Federal Efforts to Combat the Opioid Crisis, 2017, p.2).

D. Sample sentence three with evidence to support the main topic : According to Perez-Pena (2017), the Center for Disease Control and Prevention reported more than 25,000 people in the United States died in 2015 from overdosing on opioids Fentanyl, Oxycodone, and Hydrocodone.

E. Toward the end of the introduction, include your thesis statement written in the 3rd-person point-of-view: Sample thesis statement : Potential solutions to the growing opioid epidemic may be illuminated by examining how opioid addiction is triggered through aggressive pharmaceutical marketing, how opioid addiction manifests among prescribed patients, and how economic downturns play a role in the increase of opioid addiction.

F. Write down the library sources you can use in this introductory paragraph to help support the main topic.

B. Now provide sentences with evidence to support the first cause: Sample sentence one with evidence that supports the first cause : Perez-Pena (2017) concluded that while the healthcare industry was attempting to effectively and efficiently treat patients with chronic pain, pharmaceutical companies were providing funding to prominent doctors, medical societies, and patient advocacy groups in order to win support for a particular drug’s adoption and usage.

C. Sample sentence two with evidence to support the first cause : In fact, pharmaceutical companies continue to spend millions on promotional activities and materials that deny or trivialize any risks of opioid use while at the same time overstating each drug’s benefit (Perez-Pina, 2017).

D. Next, add more information or provide concluding or transitional sentences that foreshadows the upcoming second cause: Sample concluding and transitional sentence that foreshadow the second cause : Although aggressive marketing by pharmaceutical companies played a large role in opioid addiction, patients are to blame too, as many take advantage of holes in the healthcare provider system in order to remedy their addiction.

E. Write down the library sources you can use in this body paragraph to help support the first cause:

How to Start an Informative Essay?   

Before you can start writing, you have to do some "rewriting." Here are the steps involved in prewriting: 

• Brainstorm Ideas 

Brainstorming is the first step in writing any type of essay . Here, you brainstorm several topic ideas and generate a list of potential topics. 

So think about all the possible ideas that are related to your interest and subject. This will help you choose an interesting topic for your essay.  

• Choose a Topic 

Choosing the right topic is essential for writing a great essay. A good topic will not only make your writing process easy but also make the research phase interesting. 

So choose a topic you can easily write about and support it with facts, evidence, and statistics. In short, the topic should be interesting and easy to research.

• Know Your Target Audience 

Your audience determines the style and tone of your essay. Consider who will be reading your essay and what their background, knowledge, and interests might be.

For instance, if you are writing for school children, your language should be simple, easy, and interesting. Meanwhile, writing for a professional audience requires you to use technical terminology and jargon. 

So always think about who you are writing for and determine your audience before proceeding.

• Do the Research 

You have to do some research to gather information for your essay. Make sure the information that you collect is reliable and accurate. 

Use a variety of sources for research, including research articles, books, documentaries, etc. You should also take detailed and organized notes to keep track of the information you find, so you can use it later.

• Create an Outline 

An essay outline helps the writer keep their focus strong and narrow. With the help of an outline, you will easily organize your thoughts and ideas. 

So create an outline of your essay to lay out a structure.
