What is Description?

Legal Definition
Description is one of four rhetorical modes (also known as modes of discourse), along with exposition, argumentation, and narration. Each of the rhetorical modes is present in a variety of forms and each has its own purpose and conventions. The act of description may be related to that of definition. Description is also the fiction-writing mode for transmitting a mental image of the particulars of a story. Definition: The pattern of development that presents a word picture of a thing, a person, a situation, or a series of events.
