An expository essay is a type of writing that aims to explain, inform, or describe a specific topic. It presents facts, statistics, and examples to help the reader understand the subject clearly. Unlike persuasive essays, expository essays do not include the writer's opinions or emotions; instead, they focus on providing objective information. Typically structured with an introduction, body paragraphs, and a conclusion, an expository essay may cover various topics, such as historical events, scientific concepts, or social issues. This format allows writers to organize their thoughts logically and present information in a straightforward manner, making it accessible to readers.
