What type of writing is primarily used to inform the reader?

Expository writing is primarily used to inform the reader by presenting factual information, explaining concepts, or providing an analysis of a topic. This type of writing is characterized by its clear, straightforward approach, often utilizing a logical structure that helps the reader understand complex ideas. Expository writing is devoid of the author's opinions or emotions, focusing instead on delivering objective information, which makes it an ideal choice for educational texts, reports, and instructional materials.

While narrative writing tells a story, persuasive writing aims to convince the reader of a particular viewpoint, and descriptive writing focuses on painting a vivid picture through sensory details, none of these forms primarily aim to inform in the way expository writing does. Each of the other writing styles serves distinct purposes that differ from straightforwardly delivering information.
