Example:

“Write an essay explaining how email has changed the lives of students.”

As always, a close look at the instruction is essential. Here, there is nothing in the writing prompt that indicates that any kind of argument or opinion is needed. The instruction is simply to “explain.”

The goal here is provide information in as clear, concise and logical a manner as possible. Good exposition writers include journalists who are required to provide just the facts without the frothy emotional appeal of an argumentative piece.

Expository Essay

Organize your essay. Most expository essays are comprised of five paragraphs. See our guide on How To Write the Five Paragraph Essay for insight into how best use that format to construct your essay.
