On the relevance and accountability of dialect: Conversation analysis and dialect contact

The present study seeks to illustrate how the theory and method of conversation analysis (CA) can be used to begin to unpack the notion of ‘contact’ in contact linguistics research. After reviewing language and dialect contact as they are traditionally conceptualized, we describe an additional set of questions inspired by CA's fundamental concern with relevance and accountability. It is argued that, by analyzing the structure and design of turn‐by‐turn talk in situations of dialect contact, we are able to investigate how co‐participants themselves go about carving out the boundaries of their respective dialects, how they can link those dialects to social identities, and how those social identities can become ‘procedurally consequential’ for the design of subsequent talk between the interlocutors. It is ultimately hypothesized that relevance and accountability at the micro‐interactional level may provide new insight into the moment‐by‐moment mechanisms that bring about the comparatively more macro‐level outcomes of dialect contact (e.g. leveling, koineization, etc.) that have been previously identified in contact linguistics research.
