Phase, Spell-Out and Verb Movement

Chomsky (2001, 2005) claims that derivation of an expression proceeds cyclically by the phase, arguing for the phasehood of vP and CP on the ground that they are propositional , hence relatively independent at the interfaces. In this article we generally agree with phases but defining phases as propositional is problematic in that propositional is a semantic notion, which cannot be applied to syntax. Assuming that verbs undergo head movement in the syntax, we define phasehood by hosting the raised verb of a lower verb through head movement. Thus vP and CP are defined as phases due to fact that V-to-v and T-to-C occurs. It is concluded that if head movement occurs on derivations, CHL recognizes that there is no more extending on derivations and then proceeds the corresponding phases to be shipped to Spell-Out. Thus head movements are considered to be a sort of sign to CHL that phases are completed and should be shipped to Spell-Out.
