ON EXTRAPOSITION AND EXPLETIVE-MOVEMENT
Movement analyses of extraposition such as Baltin's (1982) have been called into question by the base generated adjunction analyses of extraposition proposed in Gueron and May (1984) and Culicover and Rochemont (1990) and by the base generated VP-internal analysis of extraposition proposed in Haider (1993). In this paper, however, I defend a movement analysis of the extraposition data illustrated in (la). Following Kayne's (1993) claim that extraposed constructions are formed by leftward movement, I argue that (la) is derived via leftward movement of the expletive from (Spec CP] position to (Spec AGR..P] position (in the same way that (lb) is derived by the leftward movement of the NP "Sue" from (Spec IP) to [Spec AGRnP)).
