The Derivation of VO and OV takes a new look at the relationship between head-final or OV structures and head-initial or VO ones, in light of recent work by Richard Kayne and others. The various papers in the volume take different positions with respect to whether one type of structure is derived from the other, and if so, which of the two orders is primary. Different options explored include derivation of VO order by head movement from a basic OV structure, derivation of VO by fronting of a phrasal VP remnant containing only the verb, derivation of OV by fronting of a remnant VP which the verb has vacated, and others. Each paper is thoroughly rooted in empirical observations about specific constructions drawn either from the Germanic languages or from others including Finnish, Hungarian, Japanese, and Malagasy.
