This article provides a conversation analytic description of a previously unstudied conversational action: ‘articulating the unsaid’ via and-prefaced formulations of other people’s talk. Contributing to the extant research on formulations and on interactional functions of discourse markers, the article shows that and-prefaced formulations accomplish a distinct conversational action that has the following features: these formulations are assertions about the addressee’s domain of knowledge that perform a repair operation in the form of a request for confirmation; they articulate a ‘missing’ element (...) of the addressee’s preceding talk ; what is being formulated is claimably inferable from the prior talk; moreover, such formulations extend the addressee’s course of action on his/her behalf. The article describes compositional and sequential features of and-prefaced formulations and how they shape interactional trajectories of in-progress courses of action. (shrink)
