On the basis of the meticulous transcription/observation process of 'Conversation Analysis', this book observes recurrent patterns in sequences where Japanese speakers negotiate agreement and disagreement. It contributes to the growing body of research on 'interaction and grammar' by examining how linguistic recourses are utilized for constructing turns and anticipating the upcoming course of interaction. More specifically, it focuses on the recurrent use of two structurally different types of connective expressions: clause-initial connectives and clause-final connective particles.
