This paper investigates a class of misapplication effects arising in reduplication and copy-epenthesis, specifically those relating to the assignment of phonological properties related to prominence. We argue that extensions of Correspondence Theory (McCarthy & Prince 1995) can explain these effects, given a grammar that contains: (1) a correspondence relation between surface segments, arising when multiple output segments correspond to a single input segment (also Struijke 2000, McCarthy 2002); and (2) faithfulness constraints requiring identity among these correspondents for suprasegmental properties. We show that a grammar with these properties provides a unified account of a range of prosodic misapplication effects.
