Adjacency, PF, and extraposition

In the OV Germanic languages, certain verbs selecting infinitival complements (roughly, the restructuring predicates) appear to form a tight cluster with the heads of their complements. This is particularly striking in Dutch, where clustering is overtly signaled in some contexts by an inversion of the order of the two verbal heads (assuming a head-final base order). This inversion motivated the original movement (verb raising) analysis in Evers (1975) whereby the embedded verb adjoins to the selecting head, as indicated in (1b). An alternative analysis without syntactic head movement, offered by Haegeman and Van Riemsdijk (1986), takes the inversion to be a PF phenomenon, as sketched in (1c).
