Celtic languages
The Celtic languages (usually /ˈkɛltɪk/, but sometimes /ˈsɛltɪk/ in the US) are a group of related languages descended from Proto-Celtic. They form a branch of the 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 made the explicit link between the Celts described by classical writers and the Welsh and Breton languages.
