Аннотация:This paper explores a novel case of contact-induced change due to micro-contact within Italy, where various Italo-Romance languages coexist (Standard Italian, Italiano Regionale ‘regional Italian’, and numerous local languages). Although morphosyntactic change due to micro-contact is probably widespread across Italy, it has received almost no attention in the literature. This case study involves the complementizer system of the local language Ferentinese (Southern Lazio), which underwent restructuring over a very brief period. I claim that this change is a case of downward reanalysis from Force to Fin within the split CP, triggered by the regression of the subjunctive and its subsequent replacement by a new complementation strategy. In turn, I argue that this change was the by-product of an increase in the number of complementizers in the language, from two to three, due to micro-contact between Ferentinese and Italiano Regionale. Crucially, the latter furnished a complementizer form (che) identical to one already present in the Ferentinese system, leading to reanalysis. Thus, in addition to reporting on a novel case of micro-contact in Italy, this paper illustrates one pathway to the genesis of a rare three-way complementizer system and sketches an initial typology of how related complementizer systems have changed in diachrony.
