Title: An accommodation-based approach to conventional implicature
Abstract: 

Conventional implicatures (CIs), such as the content of appositives and expressives, constitute a class of projective content distinct from presuppositions, because they normally provide new information to the discourse. Although early work (e.g., Potts 2005) regarded CIs as belonging to an independent "dimension" that is semantically inert from the at-issue content, subsequent research has pointed out various interactions between the two dimensions, posing the challenge of explaining how CIs project while still allowing those interdimensional dependencies. Against this backdrop, this talk presents an approach that accounts for the projection behavior of CIs via the mechanism of presupposition accommodation. First, I motivate this idea by presenting some systematic similarities between CIs and presuppositions regarding (i) their sensitivity to the local context and (ii) their ability to feed anaphoric dependencies. Then, I formalize the proposal based on a type-theoretical theory of presupposition, which derives interdimensional dependencies through an inferential process called type checking
