• In social interaction, different kinds of word-meaning can become problematic for participants. This study analyzes two meta-semantic practices, definitions and specifications, which are used in response to clarification requests in German implemented by the format Was heißt X (‘What does X mean?’). In the data studied, definitions are used to convey generalizable lexical meanings of mostly technical terms. These terms are either unknown to requesters, or, in pedagogical contexts, requesters ask in order to check the addressee’s knowledge. Specifications, in contrast, clarify aspects of local speaker meanings of ordinary expressions (e.g., reference, participants in an event, standards applied to scalar expressions). Both definitions and specifications are recipient-designed with respect to the (presumed) knowledge of the addressee and tailored to the topical and practical relevancies of the current interaction. Both practices attest to the flexibility and situatedness of speakers’ semantic understandings and to the systematicity of using meta-semantic practices differentially for different kinds of semantic problems. Data are come from mundane and institutional interaction in German from the public corpus FOLK.
