||This thesis proposes a sketch description of Brazilian Bergamasch, a Gallo-Italian language spoken in the town of Botuverá, in the southern Brazilian state of Santa Catarina. Brazilian Bergamasch is a non-standard variety of Bergamasch, an Italian language currently spoken in the Italian region of Lombardy, which was brought to Brazil by Italian immigrants in the late 19th century. This thesis has two main goals. Firstly, it aims to provide a grammatical and sociolinguistic sketch of the language, since Brazilian Bergamasch is currently undescribed. The description focuses on the analysis of the sociolinguistic situation present in the community, as well as on the main linguistic structures of the language (lexicon, phonology, morphology, syntax). In both cases, emphasis is given to the features that diverge from the standard variety spoken in Italy. On the basis of numerous discrepancies due to the geographic origins of the community founders on the one hand, and language internal and contact induced change on the other hand, it is argued that Brazilian Bergamasch can in fact be classified as a linguistic system independent from Standard Bergamasch. Secondly, the thesis provides a short wordlist of the basic lexicon of the language. The wordlist, which counts around 770 items, is organized by semantic fields and aims to contribute to projects of language maintenance that are currently being discussed and implemented by the community.
