This paper investigates the sluicing construction in English. It has been assumed by Merchant (2008) among others that remnant wh-phrases in sluicing undergo wh-movement, just as in non-elided cases. By demonstrating that remnant wh-phrases in sluicing show the same behaviors as wh-phrases in situ, on the other hand, I argue that remnant wh-phrases can be in situ at least in certain cases, introducing the movement theory by Agbayani (2000,2006) and Agbayani and Ochi (2006), which is consistent with the wh-in-situ analysis of sluicing. The wh-in-situ analysis proposed in this paper gives a new perspective to the language parameter regarding wh-movement in that wh-in-situ strategy can operate in English single wh-questions.
