The local speech is called "Canzés" or "Canzées", a dialect of the Insubric or Western Lombard language It is recognized by UNESCO as one of the two branches of Lombard. The central variety of Western Lombard is the Milanese dialect, which is used as a lingua franca for all Western Lombard speakers. The Canzés dialect culturally belongs to the Brianzöö dialect's family, as influenced by 19th century Milanese, Comasco and Lecchese dialects. The substratum of Canzo's primitive population further separates it from other Brianzöö dialects. For example, in phonetics you can see the prevalence of the vowel /a/ instead of Milanese /e/ or common Brianzoeu /u/. Its lexicon is conservative in comparison with surrounding dialects and modern Milanese. Its grammar employs a wide variety of registers, e.g. "noble" (similar to Old Milanese, but with strong idioms and conservative pronunciation), "commercial" (with many influences, especially from Lecchese and southern Brianzöö), "peasant" (prevalence of idioms and few similarities to Erba and Asso dialects), and "alpée" (with proper phonetic and lexical idioms). A major difference from Milanese pronunciation is the absence of vowel nasalization, rendered in Canzés with the velar nasal consonant, and the conservation of /ts/ instead of Milanese /s/, as in the pronunciation of the toponym "Canz", along with the absence of Milanese half-geminates. Like the other conservative Brianzoeu dialects, Canzés has a certain number of original Lombard terminations in /tʃ/ (spelled as "cc"): typically, "lacc" ("milk"), "frècc" ("cold"), "tècc" ("roof"), "nòcc" ("night"), "tücc" ("everybody").
