Expository

Expository refers to a mode of writing or speech whose primary purpose is to explain, describe, define, or inform. It presents information in a clear, straightforward manner and avoids elements of fiction, personal opinion, or persuasive argument. The aim is to convey understanding rather than to entertain or argue a point.

Etymology and scope: the term derives from Latin expositus, meaning “set forth.” Expository writing encompasses a range of formats, including textbook chapters, encyclopedia articles, manuals, scientific reports, and many journalistic and educational texts. It is common in academic and professional contexts where clarity and accuracy are essential.

Key features: expository texts emphasize objectivity, logical organization, and explicit evidence. They use precise language, defined terms, and careful definitions. Writers typically rely on facts, data, examples, and explanations rather than personal feelings or creative imagery. Transitions and signaling phrases help readers follow the progression of ideas.

Common structures: the genre employs patterns such as definition, description, cause and effect, comparison and contrast, process analysis, and problem-solution. Texts are usually organized around a central thesis or main idea, supported by topic sentences and coherent paragraphs.

Relation to other genres: expository writing differs from narrative writing, which tells a story, and from persuasive writing, which seeks to convince. It also contrasts with descriptive writing, which focuses more on sensory detail.

In education and professional use, expository writing develops critical reading and clear communication, equipping readers to understand complex information efficiently.
