Interacting alternatives: referential indeterminacy and questions

Floris Roelofsen

One of the major challenges involved in developing semantic theories is that many constructions in natural language given rise to alternatives. Different sources of alternatives have been identified—e.g., questions, indeterminacy, focus, scalarity—and have been investigated in quite some depth. Less attention, however, has been given so far to the question how these different kinds of alternatives interact. I will focus in this talk one one such interaction, namely between referential indeterminacy and questions. Several formal semantic frameworks have been developed to capture referential indeterminacy (dynamic semantics, alternative semantics) and the content of questions (e.g., alternative semantics, structured meanings, partition semantics, inquisitive semantics). I will report on ongoing work with Jakub Dotlacil, which aims to merge dynamic and inquisitive semantics in a principled way. I will present a basic system and suggest some potential applications and extensions.
