Celtic languages 凯尔特语族
(重定向自Q Celtic)
The Celtic languages (usually pronounced but sometimes ) 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, following Paul-Yves Pezron who had already made the explicit link between the Celts described by classical writers and the Welsh and Breton languages.
