The projection pattern of the existential/uniqueness presupposition of a wh-complement varies depending on the predicate that embeds it. This variation poses problems for existing accounts that treat the presupposition as a semantic contribution of an operator merging with the wh-complement or of the embedding predicate. I propose that the problems can be solved if the existential/uniqueness presupposition is contributed by the propositions corresponding to the answers of the embedded question, under the Hamblin/Karttunen semantics for questions.

Clause-embedding predicates come in three major varieties: responsive predicates are compatible with both declarative and interrogative complements; rogative predicates are only compatible with interrogative complements; and anti-rogative predicates are only compatible with declarative complements. It has been suggested that these selectional properties are at least partly semantic in nature. In particular, it has been proposed that the anti-rogativity of neg-raising predicates like believe comes from the triviality in meaning that would arise with interrogative complements. This paper puts forward a similar semantic explanation for non-veridical preferential predicates such as hope, which are anti-rogative, unlike their veridical counterparts such as be happy, which are responsive.
