This document outlines four main patterns of development for writing: description, narration, analysis, and argumentation. Description details what something looks like and its characteristics. Narration describes what, when, and where something happened. Analysis should explain, illustrate, clarify, or explicate something in a way that it becomes clear for readers, and can take the form of cause and effect, classification, compare and contrast, definition, or process description. Argumentation includes discursive essays, which present views on both sides of an issue in a balanced manner, and persuasive essays, which use logic and facts to show a particular point of view is more legitimate.
