The Strange Case of the Gallo-Italic Dialects of Sicily: Preservation and Innovation in Contact-Induced Change

The Gallo-Italic dialects widespread within central–eastern Sicily represent the result of the medieval immigration of settlers from southern Piedmont and Liguria, after the Norman conquest of the island (1061–1091). As far as the language spoken by these communities is concerned, an oddity arises: most of their lexical and syntactic features developed further through contact with neighboring varieties (such as, most notably, Sicilian), whereas, at a phonetic/phonological level, they have remained very conservative, largely maintaining their original northern characteristics. In the present paper, the possible causes underlying such a split are discussed: if the transfer of syntactic structures can be triggered by the presence of bilingual speakers who become progressively dominant (that is, more proficient) in Sicilian as L2, the preservation of the main phonetic/phonological features can represent a tool employed to the ends of emphasizing the identity of these new settlers from both an ethnic and linguistic perspective.
