The syntactic encoding of conventional implicatures in Sicilian polar questions

This paper describes and analyses two discourse particles that are found in polar questions and in some declarative structures in central Sicilian. The analysis adopts an interface approach, relying on the cartographic framework. It is proposed that each particle conveys in all its uses one and the same conventional implicature, relating to the epistemic state of one of the discourse participants. The interaction of the two particles with left-peripheral elements, in particular topics, vocatives, fronted foci, and speaker-oriented adverbs, supports the view that the speaker, the hearer, and the commitment anchor are syntactically represented in sentence structure.
