The Cornish language is a Celtic language that originated in Cornwall, a region in the southwest of England. It is part of the Brythonic branch of the Celtic languages, which also includes Welsh and Breton. Although it experienced a decline in the 18th and 19th centuries, efforts to revive it began in the 20th century, leading to a growing number of speakers today. Cornish is recognized as a minority language and has been granted official status in some contexts. It is taught in schools and used in cultural events, promoting the rich heritage of Cornwall and its unique identity.
