Rule Ordering in Verb Cluster Formation

This paper addresses two puzzles in the domain of verb cluster formation and proposes a solution in terms of rule ordering. The first puzzle is the socalled extraposition paradox where extraposition can target a VP that is part of a verb cluster only if the VP is topicalized but not when the VP remains clause-final. I propose that verb cluster formation takes place at PF under adjacency and thus after extraposition and topicalization. Extraposition and topicalization can therefore bleed cluster formation, leading to a crash of the derivation if the VP remains in-situ. The second puzzle involves the placement of the infinitival marker te/zu in Dutch and German. I will show that the cross-linguistic differences in placement follow from the fact that the rule that associates the particle with the verb takes place at different points of the PF-derivation in the two languages. While it is an early operation in Dutch and is still sensitive to hierarchical structure, it is a late process in German and is therefore subject to linear order and adjacency. Both operations interact with other PF rules, and I will demonstrate that it is possible to determine a strict and non-contradictory (and predominantly intrinsic) ordering of the rules which as a side-effect provides evidence for the articulation of the PF-component. Finally, I will show that the zu-placement facts do not provide decisive evidence in favor of either a right-branching or a left-branching VP-structure; rather, the advantages and disadvantages of the two views turn out to largely balance each other out.
