Romansh is a Romance language spoken by 35,000 people in the Swiss canton of Grisons (Graubünden). It is one of the four national languages of Switzerland and has semi-official status.
Romansh, which is also known as Rumantsch, Romansch or Romanche or Rhaeto-Romansch, is not in fact a single language but rather a cluster of closely-related dialects. A standardised written form, known as Rumantsch Grischun (Graubünden Romansh) was created in 1982 by Heinrich Schmid, a linguist from Zurich, though it isn't particularly popular with speakers, who prefer to use their own dialects and often use German to communicate with speakers of different dialects.
