The article aims to discuss the presence of dialect words in the Italian language as well as to evaluate the knowledge of these words by students in the last year of Italian Studies at University of Silesia. Popular dialecticisms in the Italian language will be described, and how they differ from regionalisms and geosynonyms will be explained. The main purpose is to answer the question of what the students’ knowledge of dialecticisms is and if there is a need to find space in the training process offered by the University to introduce assignments aimed at studying the formation and provenance of the Italian vocabulary.
