Wh-phrases in English can appear both raised and in-situ. However, only
in-situ wh-phrases can take semantic scope beyond the immediately enclosing
clause. I present a denotational semantics of interrogatives that naturally
accounts for these two properties. It neither invokes movement or economy, nor
posits lexical ambiguity between raised and in-situ occurrences of the same
wh-phrase. My analysis is based on the concept of continuations. It uses a
novel type system for higher-order continuations to handle wide-scope
wh-phrases while remaining strictly compositional. This treatment sheds light
on the combinatorics of interrogatives as well as other kinds of so-called
A'-movement.Comment: 20 pages; typo fixe
