What type of writing aims to inform or explain a topic?

The type of writing that aims to inform or explain a topic is expository writing. This kind of writing is designed to present information clearly and straightforwardly, often using facts, statistics, and examples to help clarify a subject for the reader. The primary goal is to educate the audience about a particular topic without trying to persuade them or tell a story.

In contrast, descriptive writing focuses mainly on painting a vivid picture of a person, place, thing, or event, often appealing to the senses, while persuasive writing seeks to convince readers to adopt a specific viewpoint or take a particular action. Narrative writing tells a story and generally includes characters, a plot, and a setting. Each of these forms has its distinct purpose and style, but expository writing uniquely fulfills the need to inform and explain.
