Rotvælsk was a secret language (also known as a cant or cryptolect) that was spoken in Denmark from early modern times until the turn of the 20th century. Rorvælsk was also known under several other names. It is now extinct. Rotvælsk was used by a social group known as Natmændsfolk who did simple craftsmanship, demeaning and unclean work or panhandled to survive. Both the social group and the language changed through the centuries, but remained associated with crime, loose morals, poverty and low social status in the eyes of the surrounding population. The social group and their language have often been confused with Romani people and the Romani language, though they do not seem to have had a different ethnic origin than most danes at that time.
