Morphologically conditioned intervocalic rhotacism in Algherese Catalan
This paper provides an analysis of the morphological and lexical conditionings determining the triggering or the blocking of the rhotacism pattern observed in Algherese Catalan. In this dialect, laterals and dental stops rhotacize in intervocalic position; the process, however, exhibits some variation mainly conditioned by the area of the word in which the intervocalic segment occurs (the left edge of the root, the root or the suffix) and the type of word in which it is contained (an inherited word or a loan). Our proposal is to account for these facts by means of lexically indexed constraints targeting exceptional behaviors in the lexicon. The article also analyzes the functional interpretation of this pattern of rhotacism, and finally reflects on the changes in the lexicon as a reflection of the process of language substitution in Algherese Catalan.
