In general the ‘Celtic’ language is divided into two branches: P-Celtic which includes the languages spoken by the Gallic and Brythonic Celts. The other is Q-Celtic which includes the languages spoken by the Celtiberians and Goidelic Celts. Of these among the best understood is Gaulish, which covered much of modern France, Switzerland, the Benelux, Northern Italy, and parts of Germany. Gaulish also spawned a number of dialects, the best known of which was the language of the Galatians in Asia
