Title: Structure matters: missing implicatures and their consequence for the theory of alternatives
Time: Wednesday, April 23rd, 1pm – 2pm
Location: 32-D461
Abstract: A central component to theories of conversational implicature is the delimitation of the set of alternative sentences that could have been uttered, but were not. Yet there is considerable disagreement about the mechanism underlying the computation of alternative utterances and the kind of objects that alternatives are claimed to be. Examining the domain of English aspect marking, we provide a novel case of implicatures disappearing when syntax independently rules out the alternatives required to generate them, and argue that this data supports a theory in which alternatives are syntactic objects, computed by an algorithm that appeals to the notion of structural complexity (Katzir 2007; Fox & Katzir 2011) but challenges theories in which alternatives are semantic objects, as in the focus theory (Rooth 1992), and the conceptual alternatives theory (Buccola et al. 2022).
