With some 40,000 speakers in northern Italy, the wider language Ladin, of which Nones is considered a dialect, is classified as Rhaeto-Romance, along with Friulian and Romansch (spoken in Switzerland). Although it is difficult to determine which Ladin dialect subgroups Nones should be belong to (Ampetian, Fassano, Gardenese, Badiotto), it appears to be most closely related to the dialect of the Val di Sol, a neighboring valley, and the two are sometimes grouped together as “Val di Noce.”
Ilaria Di Biasi published an important grammar in 2006, Ivana Sandri described the language in a 2003 publication, and Enrico Quaresima’s lexical data goes back to 1964, among other important studies of the language:
