Discourse analysis is the study of language use in context. It focuses on how spoken and written language is structured and how meaning is derived based on context. Key aspects of discourse analysis include cohesion, coherence, speech events, background knowledge, conversational interaction, and the cooperation principle. Cohesion refers to linguistic ties like anaphora that link parts of discourse. Coherence relies on background knowledge to interpret meaning. Speech events and interactions provide social context. The cooperation principle proposes conversational maxims like being relevant and clear that aid understanding. Overall, discourse analysis examines language patterns and pragmatics to interpret intended meanings in context.
