Beschreibung
Breton is a Brythonic language, descended from the Celtic British language brought from Great Britain to Armorica by migrating Britons during the Early Middle Ages. Like the other Brythonic languages, Welsh and Cornish, it is classified as an Insular Celtic language. Breton is most closely related to Cornish, as both are thought to have evolved from a Southwestern Brythonic protolanguage. The other regional language of Brittany, Gallo, is a Langue d'oïl derived from Latin. Breton is spoken in Lower Brittany, roughly to the west of a line linking Plouha and La Roche-Bernard (east of Vannes). It comes from a Celtic language community (see image) between Great Britain and Armorica (present-day Brittany), and even Galicia. It was the language of the elite until the 12th century. However, afterwards it was only the language of the people of West Brittany (Breizh Izel), and the nobility, then successively the bourgeoisie, adopted French. As a written language, the Duchy of Brittany used Latin, switching to French in the 15th century.
