The Mother Goose and Grimm strip for 1/29
turns on an ambiguity in the VP, which is of the form:
want/need + NP1 + in NP2
The ambiguity appears more generally, in VPs of the form:
want/need + NP + PredicativeComplement
The ambiguity involves two different constituent structures for the VP, with concomitant differences in the argument structures, and indeed, in the semantics of the primary verbs of desire, want and need: desiring a thing — the much more common semantics, seen in Mother Goose’s assertion:
I want that dress in the window
— versus desiring a change of state (an inchoative ‘I want that dress to be in / get into the window’ or causative ‘I want that dress to be put into the window’ reading), presupposed by Grimmy’s objection:
But that dress is in the window
