This article develops an analysis of a pair of morphological alternations in K’ichee’ (Mayan) that are conditioned at the right edge of intonational phrase boundaries. I propose a syntax-prosody mapping algorithm that derives intonational phrase boundaries from the surface syntax, and then argue that each alternation can be understood in terms of output optimization (Mascaró 2007; Mester 1994). The important fact is that K’ichee’ requires a prominence peak rightmost in the intonational phrase, and so the morphological alternations occur in order to ensure an optimal host for this prominence peak. Finally, I consider the wider implications of the analysis for the architecture of the syntax-phonology interface, especially as it concerns late-insertion theories of morphology (Anderson 1982, 1992; Embick and Noyer 2001; Halle and Marantz 1993; Hayes 1990, among others). The primary result is that late lexical insertion must occur at least as late as the construction of intonational phrases.
