All language is, to a varying extent, poetic. Investigating the relationship between conversational and literary discourse illuminates the workings of conversation. Past research suggests the pervasiveness of repetition, and its significance in questioning prior theoretical and methodological assumptions. Repetition functions in production, comprehension, connection, and interaction. The congruence of these levels provides a fourth, over-arching function in coherence, which builds on and creates interpersonal involvement. Examples illustrate the pervasiveness, functions, and automatic nature of repetition in taped, transcribed conversation—supporting a view of discourse as relatively pre-patterned, rather than generated. Repetition is a resource by which speakers create a discourse, a relationship, and a world.
