According to its UNESCO classification, the Corsican language is now in danger of becoming extinct. The language is separated into two dialects, "Northern Corsican", spoken in the Bastia and Corte areas, and "Southern Corsican", spoken around Sartene and Porto-Vecchio. The dialect of Ajaccio has been described as in transition. The dialects spoken at Calvi and Bonifacio are like the Genoa dialect, also known as Ligurian.
