Abstract

In communicative exchanges one of the most familiar phenomena is _accommodation_, which enables the addressee to incorporate a missing piece of information into her own view of the common ground. A less familiar, but equally important, phenomenon is what I call _discommodation_, whose main feature consists in the fact that the missing piece of information, although essential to the comprehension of the utterance, _cannot_ be shared by the addressee because it sounds problematic or even false to her. In such cases it is possible to open a ‘presuppositional slot’ to take into account the assumptions that serve to select the reference of the noun phrase, but that are not incorporated into the revised context. One of the main purposes of the paper is to propose a definition of truth that does not ignore the role of discommodation when different views of the common ground are involved. 1
