Servigliano revisited: An examination from constraint-based serialism

Abstract

This paper examines a metaphonic chain shift in Servigliano (Italo-Romance), in which /ɛ, ɔ/ raise to [e, o] and /e, o/ raise to [i, u] when stressed and followed by inflectional /i, u/. The paper also explores pre-tonic metaphony, whereby /ɛ, ɔ/ raise all the way up to [i, u] when followed by a stressed high vowel. First, an analysis of the data is developed using Optimality Theory with Candidate Chains (OT-CC), taking as a starting point the parallel OT analysis developed in Mascaró (2011). Second, it is shown that OT-CC causes one analytical problem and no gain in terms of economy. On the one hand, the metaphony-triggering constraint Agree(+high,+ATR) proposed in Mascaró (2011) needs to be split into two different constraints, one of which needs a more complicated formulation that requires a conditional clause. On the other hand, positional faithfulness is needed, as in the parallel OT analysis by Mascaró (2011b), to explain the asymmetry between one-step metaphony and fell-swoop pre-tonic metaphony; OT-CC provides no inherent advantage in explaining this asymmetry.
