Romansh has been recognized as one of four "national languages" by the Swiss Federal Constitution since 1938. It was also declared an "official language" of the Confederation in 1996, meaning that Romansh speakers may use their language for correspondence with the federal government and expect to receive a Romansh response. (Although Romansh is split into several dialects, the federal authorities use the standardized version ("Romansh Grischun") exclusively.)
