This thesis presents a morphosyntactic description of the Alpine Occitan language spoken in Usseaux, a small village located in Val Chisone (Italy, Province of Torino). The language is described following a synchronic perspective, but is also partly based on diachronic studies of neighbouring villages and valleys, and mainly on a corpus analysis. The thesis also describes the sociolinguistic profile of Usseaux’s speech community, leading to some thoughts about linguistic diversity, endangered languages and fieldwork. It also presents a phonological sketch, as well as a chapter on the written form of the language. The main issue of the thesis is to show that this language, which is located at the periphery of a linguistic area, is undeniably a variety of Occitan, but shows many common traits with the oïl language and with Francoprovençal as compared with more ‘central’ varieties of Occitan like Provençal and Languedocian.
