French "quantifiers" in questions: interface strategies

Building on an experimental study, I show that homophonous wh-phrases like qui 'who' in French correlate with prosodic differences when specificity and partitivity come into play, something not found with bare Universal Quantifiers like chacun 'each' and tous 'all'. Rather than homophony I claim that these wh-phrases are syncretic. I show that (a) wh-phrases and bare Universal Quantifiers are complex phrases, lexicalizing structures of different sizes; (b) partitivity and specificity are syntactic features. This last claim is supported by intervention effects: the interventions observed with negative and scope islands with wh-phrases in-situ are accounted for in terms of a feature-based Relativized Minimality (Starke 2001; Rizzi 2004).
