Switzerland has four official languages: principally German (65.6% total population share) French (22.8%) in the west; Italian (8.4%) in the south. Romansh (0.6%), a Romance language spoken locally in the southeastern trilingual canton of Graubünden, is designated by the Federal Constitution as a national language along with German, French and Italian, and as official language if the authorities communicate with persons of Romansh language (Article 70), but federal laws and other official acts do not need to be decreed in this language.
