Conversation analysis (commonly abbreviated as CA) is an approach to the study of social interaction, embracing both verbal and non-verbal conduct, in situations of everyday life. As its name implies, CA began with a focus on casual conversation, but its methods were subsequently adapted to embrace more task- and institution-centered interactions, such as those occurring in doctors' offices, courts, law enforcement, helplines, educational settings, and the mass media. As a consequence, the term 'conversation analysis' has become something of a misnomer, but it has continued as a term for a distinctive and successful approach to the analysis of social interactions.
