This paper aims to prove that the Vacuous Movement Hypothesis (VMH) is not acceptable. Many scholars have claimed that the VMH accounts for some phenomena concerning subject-object asymmetries, that-trace effects, and parasitic gap constructions. This paper illustrates that the VMH is problematic on both conceptual and empirical grounds. A new analysis is suggested in order to account for all the examples provided for the VMH. This paper assumes that an interrogative C has an edge feature requiring its specifier to be filled by a wh-phrase or an empty operator. Since the Superiority Condition works among the constituents of the relevant kind and overt whphrases and empty operators are different in kind, either can be attracted by an edge feature. It implies that an interrogative subject can remain in-situ if another constituent can move to CP-Spec, attracted by the edge feature of C. If there is only one wh-phrase for occupying CP-Spec, the wh-phrase must move to CP-Spec to satisfy the edge feature whether it is a subject or a non-subject. (Kongju National University)
