On the nature of the antiagreement effect: Evidence from wife-in-situ in Ibibio

Research output: Contribution to journalReview article

The Ibibio language displays an antiagreement effect (AAE), in which &Phi-feature agreement on the verb is suppressed in subject questions, even when the wh-phrase remains in situ. I discuss why this fact is problematic for existing theories of the AAE. I then suggest that the AAE arises when the deletion process that applies to copies in a movement chain removes the Φ-features of a copy along with its semantic features. This formulation applies equally well, to overt and covert whmovement. It also generalizes to explain why quantified subjects do not trigger an AAE in Ibibio, whereas subjects in negative clauses do.
