Structurally Similar Formats Are Not Functionally Equivalent across Languages: Requests for Reconfirmation in Comparative Perspective.

This study is concerned with a cross-linguistic comparison of requests for reconfirmation (RfRCs) in Yurakaré, German, and Low German mundane spoken conversations. We focus on two different RfRC formats, namely token RfRCs (such as German echt? 'really') and RfRCs that repeat (part of) another speaker's prior turn. We show that these RfRC formats are used to accomplish different social actions in the three languages under study, ranging from registering news to challenging prior information. Token RfRCs serve as versatile resources for responding to news in all three languages. Repeat RfRCs, in contrast, are used in divergent ways: In German, they are mainly treated as challenges, while showing only a weak contextualisation of challenges in Low German and virtually no potential for being understood as challenges in Yurakaré. Our study thus demonstrates that structurally similar RfRC formats can be put to use for different actions and sequence trajectories across languages. [ABSTRACT FROM AUTHOR]
