The Cornish and Manx languages became extinct in modern times. Welsh is the only Celtic language not classified as endangered by UNESCO.

Welsh is an official language in Wales and Irish is an official language of Ireland and of the European Union. All are minority languages in their respective countries, though there are continuing efforts at revitalisation. There are six living languages: the four continuously living languages Breton, Irish, Scottish Gaelic and Welsh, and the two revived languages Cornish and Manx. Today, they are restricted to the northwestern fringe of Europe and a few diaspora communities. ĭuring the first millennium BC, Celtic languages were spoken across much of Europe and central Anatolia. The term "Celtic" was first used to describe this language group by Edward Lhuyd in 1707, following Paul-Yves Pezron, who made the explicit link between the Celts described by classical writers and the Welsh and Breton languages. They form a branch of the Indo-European language family. The Celtic languages ( / ˈ k ɛ l t ɪ k/ KEL-tik) are a group of related languages descended from Proto-Celtic.
