Work on the movement of phrase categories, mostly Noun Phrases, has been a central element of syntactic theorizing almost since the earliest work on generative grammar. Work on the movement of lexical elements, heads, has been much less central until recent years. Verb movement is now, however, the center of current research in syntax. Parallel to the theoretical interest has been the attention focused on the description of verb-second languages and on the movement operations that place the verb in its "second" position. This volume represents the latest work from many of the leading researchers in an important field, and draws on analyses from a wide range of languages. It will have a significant impact on its field.
