Before writing or undertaking this task always have a clear mind about what topic you will select. Having your selection narrowed down to one or two topics is the best practice. When you’ll have the topic then it will be easy to know how to write an expository essay. 

After the topic selection, you will find the research available either in books or on the internet. It is important that information that is available or retrieved through online platforms should be credible. Because you are supposed to write facts, not rumors. Thus maintaining a writer’s credibility and integrity is of cardinal importance.

Look at the following steps in detail on how to write an expository essay

Topic Selection Before Writing an Expository Essay

As mentioned before, the topic’s selection is the make or break and requires 10/10 attention. Most of the students try to create a shortcut by undermining the value of the topic. Thus it is their downfall from the start.

Likewise, selecting a topic that has a narrow research field and credibility is a pit that is hard to get out of. There are many things that can be selected for proper research. For example, you can select “the role of cigarettes in high mortality rate in adults”. 

The above example topic has extensive research available from credible health journals like “New England Journal of Medicine”, “Mayo Clinic”, “FDA” etc. Selecting the topic that has evidence base studies available will give an authentic representation to your essay.

Similarly “Dangers of fossil fuels and melting ice-caps of polar ice” has loads of research. Choosing any topic like the mentioned ones here will surely help in good research and consequently in writing as well. 

Do the Proper Research

As soon as you choose the topic; it is time to do the research. Make a well-prepared list of citations and sources that will be mentioned when you will write the essay. If you have a book that is already written on the same topic then try to dig for more information.

Additionally, it is also possible that the previously written essays might have missed some of the core findings. This will help you add more stuff as new findings to capture the audience’s attention. 

Also, write and save all the research on paper as well as in digital form. This step will help you when you will be composing the final draft of the essay. A well-written expository essay should have two to three sources mentioned. Writing around the gathered facts gives a proper outline on which the entire essay will be based.

Relax and Make a Mind Map Before putting pen to the Paper

As soon as you finish your research work, try to relax for a few hours. It is better to utilize a mind map to structure your essay. Write all the ideas on one big chart or a board and gather all your thoughts. 

Immediately after getting the thoughts sorted and refined; it is time to write. Take all the headings from the mind map and put them on paper.

On the other hand, only pause when ideas are finished in your mind. Stopping, again and again, will create a gap in your thinking and writing abilities. Thus, continuous momentum is vital to keep the smooth running of your composition.

Make a Good Introduction

Make a Good Introduction

After selecting the topic, doing research, and gathering ideas by mind map, it’s time to write the introduction. Your introduction of the essay should contain a “thesis statement” and “hook”.

An introduction is a short description of the entire research of the topic. For example, you can write how “smoking is the leading cause of death in adults”. According to your research, you have found these figures either to be true, less or completely false, etc.

Then you can summarize the outline of your essay by saying, your topic is containing facts from FDA, etc. When you claim your facts to be authentic and sound that would be your hook statement. You will capture the audience’s attention by adding new facts or simply contradicting the old myths or beliefs.

Making a bulletproof introduction is essential because 50% of the audience is lost if the introduction is poorly written. Thus as a writer, it is your duty to present a good introduction filled with interesting facts to your audience.

Present Your Evidence in Body Paragraph One

The body is the most important part of an expository essay. It can be called the heart of the entire research. Providing your evidence is the key to honing the skills of writing an expository essay. 

Additionally, expository essays are quite lengthy and thus require much evidence to be added. That’s why you can add further supporting evidence into body paragraph two.

The main highlight of the essay is the evidence you have collected. Supposedly should be unique and authentic as mentioned in the first few paragraphs line. 

Secondly, present all the collaborating statements that will show to the audience that you know about the topic as much as you claim. This makes them trust you and your thesis evidence. Try not to complicate things by using too many words, but rather concise and to-the-point references are enough for impactful words.

Present one evidence and its statement and so on. Presenting all research and pieces of evidence in one paragraph and then explaining them all is a killer for your career and writing as well.

Body Paragraph Two

After presenting one or two major pieces of evidence, it’s time to start adding the secondary evidence in body paragraph two. These are collaborating and small factual details that you will add to further strengthen your case. 

Usually, expository essays have one major piece of evidence and few witnesses to the ongoing research that is collectively called “supportive evidence”. To illustrate its effectiveness, it can explain as “Smoking causes serious health issues; many studies have shown almost 80% of heart attack victims are smokers”.

The aforementioned paragraph shows collaboration and a strong link between smoking and heart attack. Thus we can say that it’s definitely a fact that smoking causes serious health deterioration and should be avoided at all times.

Avoid Jargon and technical words

One important thing in knowing how to write an expository essay is to completely avoid jargon. Your audience is not a technical one and needs education. It’s better to use an informative tone than a persuasive one. Because in the end, you are presenting the facts, not giving a sales pitch.

Using jargon can complicate things if the words are too much difficult. Your readers will prefer to read something simple and informative rather than full of technical jargon.

Simple language can let the readers know all the things in your expository essay rather easily. Complete avoidance of jargon will create their interest even more and let them make it to the end.

The last part of getting to know how to write an expository essay is the conclusion. When you present all of the main findings, their sub findings, and shreds of evidence; it is time to give the final verdict. 

You have to summarize all the essay’s main highlights and compile them in short form. One thing is important to read the body paragraph one and two, note down important points and rephrase them in the conclusion.

A conclusion should serve as a verdict, not a repetition of words. A good starting point for writing a conclusion is to start with the following statement as 

“In the light of the evidence presented in this writing, it is clear that smoking is dangerous and causes a heart attack in adults regardless of age, gender, or race, thus the general consensus is that it should be avoided in all cases”. 

By clearly stating the facts and supportive arguments, you will be able to present the factual side of the narrative. In academic or college assignment writing, the conclusion is considered the “Holy Grail” of writing.

One important thing in writing a conclusion is to never add irrelevant information and words. Your conclusion should have one or a maximum of two paragraphs consisting of two to three lines each. 

In short, treating and making a conclusion lengthy and full of wordy sentences is a suicide mission. Hence ignore it completely altogether. 

Do Not Exceed Your Expertise

It is also very important to never exceed your expertise and choose the topic you have information about. If the topic is already provided by your professor or teacher then it’s another thing. Otherwise, always know which direction you will choose in writing.

Usually writing an expository essay seems quite easy but it’s totally the opposite. Any topic you have already information about is an easy one and should be selected as the primary choice.

A recent survey by World Economic Forum has revealed that the global population with diabetes is more than 400 million, and 300 million out of 400 are in developing countries. This is clear evidence that more and more poor population is developing diabetes and serious health conditions.
