"Conversation analysis (commonly abbreviated as CA) is the study of talk in interaction. CA generally attempts to describe the orderliness, structure and sequential patterns of interaction, whether this is institutional (in the school, doctor's surgery, courts or elsewhere) or casual conversation. Thus, use of the term “conversation” to label this disciplinary movement is misleading if read in a colloquial sense, as many have. In light of this, one of CA’s principal practitioners, Emanuel Schegloff, has more recently identified “talk-in-interaction” as CA’s topic. Perhaps for this same reason, others (e.g., Jonathan Potter) who use CA methods identify themselves as discourse analysts (DA), though that term was first used to identify researchers using methods different from CA (e.g., Levinson, 1983), and still identifies a group of scholars larger than those who use only CA methods."
