Loyalty Islands in the context of Grande Terre (New Caledonia)

New Caledonia is a French territory comprising a group of islands in the southwest Pacific Ocean, 220 km (140 mi) southwest of Vanuatu and 1,210 km (750 mi) east of Australia. Located 16,100 km (10,000 mi) from Metropolitan France, it forms a sui generis collectivity of the French Republic, a legal status unique in overseas France, enshrined in a dedicated chapter of the French Constitution and with an on-going project to a status of State of New Caledonia.

The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. French people, especially locals, call Grande Terre le Caillou, a nickname also used more generally for the entire New Caledonia. Pro-independence Kanak parties use the name (la) Kanaky (pron. [(la) kanaki]) to refer to New Caledonia, a term coined in the 1980s from the ethnic name of the indigenous Melanesian Kanak people who make up 41% of New Caledonia's population. New Caledonia is associated with the European Union as an overseas country and territory (OCT).

The geography of New Caledonia (Nouvelle-Calédonie), an overseas collectivity of France located in the subregion of Melanesia, makes the continental island group unique in the southwest Pacific. Among other things, the island chain has played a role in preserving unique biological lineages from the Mesozoic. It served as a waystation in the expansion of the predecessors of the Polynesians, the Lapita culture. Under the Free French it was a vital naval base for Allied Forces during the War in the Pacific.

The archipelago is located east of Australia, north of New Zealand, south of the Equator, and just west of Fiji and Vanuatu. New Caledonia comprises a main island, Grande Terre, the Loyalty Islands, and several smaller islands. Approximately half the size of Taiwan, the group has a land area of 18,575.5 square kilometres (7,172.0 square miles). The islands have a coastline of 2,254 km (1,401 mi). New Caledonia claims an exclusive fishing zone to a distance of 200 nmi or 370 km or 230 mi and a territorial sea of 12 nmi (22 km; 14 mi) from shore.

West Uvean (also Uvean or Faga Ouvéa; Fagauvea in the vernacular) is a Polynesian outlier language spoken on the island of Ouvéa, in the Loyalty island group of New Caledonia, and in the capital of Nouméa.

West Uvean has been studied by linguists Françoise Ozanne-Rivierre and Claire Moyse-Faurie.
