Here's the breakdown:
* French is the official language of Corsica, just like it is for the rest of France. It's used in government, education, and most public settings.
* Corsican is a regional language, spoken by a large portion of the population, particularly in rural areas. It's a Romance language related to Italian and Tuscan, and has a strong cultural significance for many Corsicans.
* Italian is also spoken, especially in the eastern part of the island, due to historical ties and proximity to Italy.
So, while French is the dominant language, Corsican and Italian are also prevalent, giving Corsica a unique linguistic landscape.
