Common Features of Italo-Carune Languages
The most notable feature of these languages is the retension of the neuter gender, lost in most other Romance languages.
Eastern Carune Languages
Mònzo and other central languages are, interestingly enough, more closely related to Spanish than Italian, Rumantsch, or the other languages in their vicinity. They lost the final -e's common in central verb infinitives, but gained a stress accent not found in the central languages.
Central Carune Languages
Carune and other eastern languages are, in contrast, much closer to Italian than the Iberian languages. They incorporate a large portion of vocabulary from Iberian languages, however.
