🔖 Types of Expository Writing

Whenever an essay or article explains complicated details or simplifies a bulk of hard-to-understand information, this type of writing is called expository.

Imagine you are talking to a curious child who keeps asking you “how” and “why” things are such or another. You need to explain everything from scratch, yet making it sound compelling. Small and peculiar details are essential here.

The principal purpose of an expository essay is to elucidate a topic logically and consistently. It is an objective analysis of facts without any reference to the writer’s emotions or opinions.

Expository Writing Types Are: Problem & Solution, Cause & Effect, Compare & Contrast, Definitions & Classfication, How-to.
Problem & solutionHere you need to identify the issue, provide its details and causes, and develop a solution. A problem can have several possible solutions, so you can list several alternatives, highlighting the best one. In such a case, dedicate one main body paragraph to one solution and be sure to explain your choice. Otherwise, if you give only one variant, describe it in detail, justify it, and propose its implementation plan.
Cause & effectThe focus of this essay is on the reason why something happened and the consequences it has entailed. The most popular examples of cause and effect expository essays are environmental problems, historical events, biodiversity issues, and economic analysis. If the predicted result is based on assumptions, it requires validation.
Compare & contrastThis essay requires you to compare the similarities of two phenomena or ideas and contrast their differences. For example, you can be asked to compare and contrast homeschooling and attending a public school. The common feature will be the teacher’s presence, but the difference is the number of pupils attending the class.
Definitions & classificationThe best example of this type of writing is this article. Here you are explained what a notion or phenomenon is and what kinds it can be divided into.
How-toThese essays describe a task and the process of its completion. E.g., in an article on how to perform a Japanese tea ceremony, you have to briefly overview this tradition and then give a step-by-step plan of its implementation.

It’s always worth clarifying with your teacher who your essay’s intended audience is if it’s not clearly stated in the instructions.

Either way, you should be mindful of who you intend to inform as you carry out your research and planning.

Choose Your Sources

You will need to find multiple sources that are relevant and reliable in order to deal with your subject matter accurately and comprehensively. Below is a checklist that might help you choose the right sources for your essay.:

✔️Author’s credentialsIs the author qualified to write about the subject?
✔️Publisher’s reputationIs the work published by a well-respected organization that has checks and standards in place?
✔️CitationsHas the author cited a sufficient number of respected sources to support his/her work?
✔️BiasDoes the author and/or publication have an agenda that might cloud the objectivity of the work?
✔️Publication dateIs the work up to date and still relevant?

Take notes as you read, and cross-check sources. Your goal is to formulate the points you need to deal with the set task and find evidence to support them.

Once you’ve completed this, you will have a clear sense of direction, and if it hasn’t already been assigned, you will be able to compose a thesis statement for your essay that meets the requirements of the task and fits your sources.
