AbstractPredicate which-appositives (PWAs) are a class of nonrestrictive, parenthetical relative clauses that take as their antecedents predicate-denoting material in the spine of a clause. PWAs contain a gap, and it is difficult to tell whether this gap is derived by a deletion operation like verb phrase ellipsis or by wh-movement. Indeed, diagnostics meant to distinguish these two possibilities provide evidence that both are correct. In order to remedy the apparent conundrum, I draw on recent work on Danish verbal anaphora. I argue that the VP itself undergoes A'-movement and that the relative operator which is inserted post-syntactically in place of the VP, replacing its phonological material. This post-syntactic operation explains why there appears to be phonological deletion involved in the derivation of PWAs while still allowing the A'-movement properties of the construction to be explained.
