 The formulation of the aim of Montague semantics mentioned in the introduction (‘to characterize truth and entailment of sentences’) suggests that the method is restricted to declarative sentences. But this need not be the case. In Montague 1973 (241 fn) we already find suggestions for how to deal with imperatives and questions. Hamblin (1973) and Karttunen (1977) have given a semantics for questions by analyzing them as expressing sets of propositions, viz. those expressed by their (declarative) answers; an alternative approach, taken by Groenendijk and Stokhof (1989) considers questions as partitioning logical space into mutually excluding possibilities.
