Celtic languages

The Celtic or Keltic languages are descended from Proto-Celtic, or “Common Celtic”; a branch of the greater Indo-European language family. The term “Celtic” was first used to describe this language group by Edward Lhuyd in 1707. 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.
