Conversation analysis (CA) and discourse analysis (DA) are two forms of analysis of language that, nevertheless, focus on quite different aspects. Conversation analysts are interested in the way language (langue) is used in interaction and how this use brings into being social organization and institutions. That is, CA focuses on talk-in-interaction. The fundamental assumption of CA is that "what a doing, such as an utterance, means practically, the action it actually performs, depends on its sequential position" (CA 6).
