Book excerpt: This book represents the state of the art on rightward movement in one thematically coherent volume. It documents the growing importance of the combination of empirical and theoretical work in linguistic analysis. Several contributions argue that rightward movement is a means of reducing phonological or structural complexity. The inclusion of corpus data and psycholinguistic results confirms the Right Roof Constraint as a characteristic property of extraposition and argues for a reduced role of subsentential bounding nodes. The contributions also show that the phenomenon cannot be looked at from one module of grammar alone, but calls for an interaction of syntax, semantics, phonology, and discourse. The discussion of different languages such as English, German, Dutch, Italian, Italian Sign Language, Modern Greek, Uyghur, and Khalkha enhances our understanding of the complexity of the phenomenon. Finally, the analytic options of different frameworks are explored. The volume is of interest to students and researchers of syntax, semantics, psycholinguistics, and corpus linguistics.
