Welsh (Cymraeg or y Gymraeg, pronounced [kəmˈrɑːɨɡ, ə ɡəmˈrɑːɨɡ]) is a member of the Brythonic branch of theCeltic languages spoken natively in Wales, by some along the Welsh border in England, and in Y Wladfa (the Welsh colony in Chubut Province, Argentina).

2.Celtic Language

Celtic languages are most commonly spoken on the north-western edge of Europe, notably in Ireland, Scotland, Wales, Brittany,Cornwall, and the Isle of Man, and can be found spoken on Cape Breton Island. There are also a substantial number of Welshspeakers in the Patagonia area of Argentina. Some people speak Celtic languages in the other Celtic diaspora areas of the United States,[3] Canada, Australia,[4] and New Zealand.[5] In all these areas, the Celtic languages are now only spoken by minorities though there are continuing efforts at revitalization. Welsh is the only Celtic language that isn't classified as "endangered" byUNESCO.
