We propose a theory of head displacement that replaces traditional Head Movement and Lowering with a single syntactic operation of Generalized Head Movement. We argue that upward and downward head displacement have the same syntactic properties: cyclicity, Mirror Principle effects, feeding upward head displacement, and being blocked in the same syntactic configurations. We also study the interaction of head displacement and other syntactic operations, arguing that claimed differences between upward and downward displacement are either spurious or follow directly from our account. Finally, we show that our theory correctly predicts the attested crosslinguistic variation in verb and inflection doubling in predicate clefts.

Harris and Halle (2005) present a framework (Generalized Reduplication) that unites the treatment of phonological reduplication and metathesis with similar phenomena in morphology, thereby accounting for the apparently spurious placement of the imperative plural - n in mesoclitic Spanish forms such as hága-lo-n ‘Do it!’, in which clitic lo is sandwiched between the verbal stem and the plural suffix. Kayne (2010) has challenged their analysis, arguing that such cases should be treated purely within the syntax. We reassess some of Kayne’s arguments, agreeing with his conclusion that the most important desideratum of any general analysis of such phenomena is restrictiveness. However, we contend that greater restrictiveness can be achieved through morphotactic constraints and repairs in the Generalized Reduplication formalism, triggered by a Noninitiality constraint on the positioning of the plural affix, and we develop constraints on these operations that situate interspeaker variation within the postsyntactic component.

In this article, we argue for a syntactic approach to the computation of stress in Spanish. Our basic claim is that stress placement in this language makes crucial reference to the internal syntactic structure of words. In particular, we propose that foot boundaries are projected from certain functional heads. The analysis is set within the framework of Distributed Morphology and uses the formalism of the bracketed grid for the representation of stress. Several hypotheses concerning the syntax of words are argued to be necessary in gaining a better understanding of stress placement in Spanish.
