Celtic languages

Celtic languages are the languages descended from Proto-Celtic, both those spoken by the ancient Celts, and those used by their modern descendants, the Irish, Manx, Scots, Welsh, Cornish and Bretons. The Celtic languages are classified as a branch of the greater Indo-European language family. They were spoken across western Europe during the 1st millennium BC, but are now limited to a few enclaves in the British Isles, western Canada, Patagonia, scattered groups in the United States and Australia, and on the peninsula of Brittany in France.
