Q-particles and the nature of Covert movement: Evidence from Buli

There are a number of intriguing issues surrounding wh-questions that have drawn considerable attention in the literature. Among the most commonly observed is the fact that in certain languages, wh-phrases move overtly from their base-generated positions to a clause-peripheral position, while in other languages the wh-phrases remain in-situ and are not overtly moved. A well known and contentious issue, to which this paper contributes with novel data from Buli, is the status of the in-situ wh-phrase. For instance, do in-situ phrases undergo covert movement? If so how is this movement similar or different from overt movement? I argue that the language distinguishes two kinds of wh-in-situ phrases: one undergoes covert movement, a movement I claim is comparable in many ways to overt wh-movement, while the other one doesn’t. The key to this observation, I further argue, is the presence of an overt Q-particle in the language. Whenever the Q-particle is absent, the signs of movement disappear. This provides a very transparent set of arguments in favor of the mixed view that sometimes you have movement of wh-in-situ and other other times you don't.
