[[English]] is universally spoken in Wales - however, the ancestral Celtic language of [[Welsh]] is still spoken as a first or second language by approximately a quarter of the population. The long-term decline in Welsh-speakers has stabilised since the early 1990s owing to the introduction of compulsory Welsh language classes in schools.
