What is an exposition?

Exposition is one of four rhetorical modes of discourse, along with argumentation, description and narration. The purpose of exposition is to inform, explain, analyze, or define. A well-written exposition is consistently focused on the topic and lists events in chronological order.

Examples of non-fiction expository writing include textbooks, research reports, scientific reports, wills and encyclopaedias.

Within the context of fiction, exposition is the mode by which information is conveyed. The information presented may be in the form of facts, explanation, or opinion and may be used for a variety of purposes, including the development of plot, character, setting, and theme.

In total, there are five types of expository writing, namely sequence writing, descriptive essays, classification writing, comparison writing and cause-and-effect writing.
