Students are typically instructed to submit papers using one of the four major writing styles: expository, narrative, persuasive, or descriptive. Expository writing is one of the more commonly known forms of writing.
Expository writing focuses on explaining or exposing a topic; in other words, it is a piece of writing that is instructive. The goal of expository writing is to expound on an idea concisely and bias-free. This style is used throughout the world in a myriad of ways. It can be found in textbooks, directions, articles like this one, and other platforms of writing seen daily. When writing an expository piece, the author or publisher is not to state their own opinions on the topic. The piece should be neutral and inform a reader without attempting to persuade.
Analysis, juxtaposition, and cause & effect are not to be confused with persuasive writing. The first three all fit into expository writing because they logically explain topics without siding with one point of view of an argument.
Expository writing is extremely prevalent throughout the news, online publications, instructions, and social media all around the world.
