The Aosta Valley was the first government authority to adopt Modern French as working language in 1536, three years before France itself.

Italian and French are nowadays the region's official languages[4] and are used for the regional government's acts and laws, though Italian is much more widely spoken in everyday life, and French is mostly used by intellectuals and within cultural events.

French remains widely known as a second language, but it is no longer spoken as part of daily life.

[5] In 2001, 75.41% of the population of Aosta Valley was French-speaking, 96.01% declared to know Italian, 55.77% Arpitan, and 50.53% all of them.

Aostan French is characterized by terms adopted from the valdôtain dialect of Franco-Provençal and sometimes from Italian.
