Variation and change in Italian phonology: On the mutual dependence of grammar and lexicon in Optimality Theory

Abstract

In this paper I discuss the influence of language acquisition and borrowing on the reorganisation of grammar and lexicon in the development from Latin into Italian. We will have a look at the historical sequencing of the introduction of new phonological processes, velar palatalization, mid vowel breaking, and lateral palatalization, and how they conspire to create new contrasts or reintroduce contrasts that have been subject to neutralisation. The amphichronic analysis proposed here brings together insights from acquisition and loanword phonology in Optimality Theory to explain the historical development.
