Bresnan ( 1971 , 1972 ) establishes an interaction between stress assignment and syntactic movement. We are interested in a restriction on this interaction. We argue that this restriction shows that the constraint S TRESS -XP needs to be part of the syntax-prosody mapping and that it needs to be a restriction on a correspondence relation between syntactic XPs and phonological phrases. (A second constraint on the correspondence relation is either W RAP -XP or M ATCH -XP.) In the course of our argument, we analyze Bresnan’s interaction between stress assignment and movement within an account in which Internal Merge induces reconstruction effects at both LF and PF.

This article argues that the relation between syntactic XPs and phonological phrases is subject to a constraint, WRAP-XP, that demands that each XP be contained in a phonological phrase. WRAP-XP is argued to interact with the constraints on edge alignment proposed by Selkirk (1986, 1995), with a constraint against recursive structure, and with a constraint aligning an edge of a focus with a phonological phrase. WRAP-XP is intended to replace, and improve on, an earlier proposal by Hale and Selkirk (1987) to the effect that lexical government plays a role in the syntax-prosody mapping. The languages discussed in more detail are Tohono O'odham, Kimatuumbi, and Chicheŵa.
