The Celtic language family is a branch of the larger Indo-European language family. It includes languages traditionally spoken in the British Isles and parts of France, such as Irish, Scottish Gaelic, Welsh, Cornish, and Breton. These languages are divided into two main groups: Goidelic (or Gaelic) and Brythonic (or Brittonic). Celtic languages are known for their unique grammatical structures and vocabulary. They have a rich cultural heritage, often associated with ancient Celtic tribes and traditions. Today, efforts are being made to preserve and revitalize these languages, as they are considered vital to the cultural identity of their speakers.
