This document provides an overview of discourse analysis as a discipline within linguistics. It defines discourse both narrowly as language above the sentence level, and widely as a social practice. Examples are given of different types of discourse, including spoken, written, and visual. Discourse is discussed as both a linguistic concept involving cohesion between language elements, and a social phenomenon influenced by issues like gender, race, and power dynamics. Key aspects of discourse analysis are outlined, such as identifying implicit power relations and alternative perspectives that could be presented.
