Breton (Brezhoneg) is a member of the Celtic language family spoken in the region of Brittany in north-western France. It developed on the continental side of the English Channel after migration from Britain in the early Middle Ages and has a distinct history from the neighbouring Romance languages.

Classification and close relatives

Breton belongs to the Brythonic branch of Celtic and is most closely related to Cornish, the language historically used in Cornwall on the south-western coast of Great Britain. It shares more distant ties with Welsh. The other branch of Insular Celtic, the Goidelic languages, includes languages of Scotland, Ireland and the Isle of Man, which are related but more distantly.

Number of speakers and current status

Recent estimates put the number of Breton speakers in the low hundreds of thousands (commonly cited figures range near 200,000–250,000), but intergenerational transmission has weakened in the past century. National language policies that emphasised French as the language of education and administration, together with social and economic pressures, have contributed to a steady decline; the role of the government of France in promoting a single national language is a significant historical factor. Because of these trends, Breton is classified as an endangered language.

Efforts to reverse decline include immersion and bilingual schooling, new media in Breton, and local cultural initiatives. The language’s future depends on continued community support, educational provision, and official recognition at regional and national levels.
