On the Clause Mate Condition in Multiple Sluicing

This paper aims to illustrate that the Clause Mate Condition, a peculiar property in multiple sluicing, is naturally accounted for under rightward movement analysis (=RMA): the second wh-phrase (=WH2) in multiple sluicing undergoes a rightward focus movement. Although WH2 moves rightward as does HNPS, there is a notable difference between WH2 movement and HNPS. HNPS is an operation involving moving a noun phrase to the edge of vP, and the noun phrase remains a part of vP after movement. On the contrary, WH2 moves rightward to the Spec of FocP, which is selected by C. For the reason WH2 in multiple sluicing escapes from deletion, because in multiple sluicing TP-deletion applies and FocP is outside TP. Moreover, the RMA has other advantages of accounting for the relevant phenomena: the asymmetry between multiple questions and multiple sluices in English with regard to pair-list and single-pair readings, and the impossibility of swiping in WH2 unlike in WH1.
