Prosodic identity in copy epenthesis: Evidence for a correspondence-based approach

This paper focuses on languages that exhibit processes of copy epenthesis, specifically those where the similarity between a copy vowel and its host extends to prosodic or suprasegmental resemblance. We argue that copy vowels and their hosts strive for identity in all prosodic properties, and show that this drive for prosodic identity can cause misapplication in the assignment of properties such as stress and length. To explain these effects, we argue that any successful analysis of copy epenthesis must involve a correspondence relation (following Kitto and de Lacy 1999). Our proposal successfully predicts the extant typology of prosodic identity effects in copy epenthesis; alternative analyses of copy epenthesis relying solely on featural spreading (e.g. Kawahara 2007) or gestural realignment (e.g. Hall 2003, 2006) do not naturally capture the effects discussed here.
