It has been well-argued in the literature that the distinction between heads and phrases is not primitive, and thus syntactic movement can affect both heads and phrases in the same way. This view predicts that we should find the same types of movement that are available to phrases also available to heads. Specifically, we should find head movement that can cross clausal boundaries and occur both overtly and covertly. In this paper, I argue that the element zenme in Mandarin Chinese undergoes covert wh-movement as a head. This element is novel both as a case of covert A-bar movement of a head and wh-movement of a head. Moreover, zenme also belongs to a class of verbal wh-elements, which have not received any attention in the syntactic literature until now.
