What Is an Expository Essay?

An expository essay is a structured piece of writing that informs or explains a subject without expressing personal opinions or arguments. It relies on research, definitions, comparisons, or processes to convey information logically. In high school, these essays typically range from 500 to 800 words and focus on topics like science processes, historical events, or social issues.

For instance, an expository essay might explain the water cycle by describing evaporation, condensation, and precipitation stages with diagrams or data.
