Breton is a Southwestern Brittonic Celtic language spoken in Brittany in northwestern France.
It is one of the six extant Celtic language (the others being Cornish, Welsh, Irish, Scottish Gaelic, and Manx).
It shares with Welsh and Cornish an identical basic vocabulary and with all other Celtic languages the grammatical use of initial consonantic variation, which is used mainly to denote gender.
Breton benefited culturally and socially from a language-recovery movement that emerged in Brittany in the late 20th century.
