The three Brythonic languages are Welsh, Cornish, and Breton. Of these Cornish became extinct in the 18th century but people have started speaking it again now. Welsh is spoken everywhere throughout Wales, but is mainly first language for people in the western part of Wales, in the area some people call the Bro Gymraeg. Breton is spoken mainly in west Brittany, and is the only Celtic language not mainly spoken on the islands of Great Britain and Ireland. Because Brittany is part of France, the language is in danger of becoming extinct, just like Cornish, and there are ongoing efforts to prevent this from happening.
