Kanak people
Kanak languages are extremely diverse, but French serves as the official language of New Caledonia. There are 28 distinct Kanak languages, as well as many dialects, out of the 1,200 Melanesian languages spoken throughout the Pacific. They are mutually incomprehensible. All are a part of the Oceanic branch of the Austronesian family. They all belong to the New Caledonian subgroup – except for Fagauvea, which is a Polynesian language.
Drehu language
Drehu ([ɖehu]; also known as Dehu, Lifou, Lifu, qene drehu) is an Austronesian language mostly spoken on Lifou Island, Loyalty Islands, New Caledonia. It has about twelve-thousand fluent speakers and the status of a French regional language. This status means that pupils can take it as an optional topic for the baccalauréat in New Caledonia itself or French mainland. It has been also taught at the Institut National des Langues et Civilisations Orientales (INALCO) in Paris since 1973 and at the University of New Caledonia since 2000. As for other Kanak languages, Drehu is now regulated by the "Académie des langues kanak", officially founded in 2007.
