Faetar is a variety of Franco-Provençal spoken in the village of Faeto in Apulia, southern Italy. The village has 615 registered inhabitants (ISTAT 2023), but a little more than 400 actually live there in a permanent way. Previous studies have demonstrated that the community is experiencing language shift, especially when it comes to younger generations (Perta 2008, Bitonti 2012), but although lexical borrowing from Italian has occurred, no extensive change is visible (Nagy 2011). This paper aims at investigating the extent to which pervasive and enduring contact between Franco-Provençal and normative Italian has influenced the perception of correctness in a specific area of grammar: objective complement clauses. Although colloquial Italian allows the usage of the indicative tense to express objective clauses, standard Italian requires the subjunctive, making it more appropriate and formal; in Faetar, on the other hand, the indicative tense has always been used, regardless of the formality of the context. The data, which have been collected through the usage of a judgement task given to people of different age groups, will be analysed to see whether pervasive contact has led to a change in the actual use of the indicative tense in Faetar in favour of the subjunctive, and whether speakers perceive the Italian-influenced subjunctive form as more appropriate and correct, inducing them to formulate their answers utilising the subjunctive.
