Sursilvan is used across most of the
Surselva District, with the exception of the
Walser villages of
Obersaxen,
Vals,
St. Martin and
Safiental. Outside of the Surselva District,
Flims is also part of the Sursilvan dialect area. In addition, Sursilvan was previously used as the written Romansh language of parts of the
Sutsilvan dialect area. When a separate Sutsilvan written language was introduced in 1944, the villages of
Bonaduz,
Rhäzüns,
Domat/Ems and
Trin retained Sursilvan as their written language. In addition, Sursilvan was previously used in the
Surmiran dialect area as the language of church, but has now been replaced by Standard Surmiran and
Rumantsch Grischun. Most municipalities in which Sursilvan is the traditional language still have a Romansh-speaking majority today. The exceptions are
Flims,
Laax,
Schnaus,
Ilanz,
Castrisch,
Surcuolm, and
Duvin. In all of these, except for Flims, however, a majority of people reported using Romansh daily in the 2000 Swiss census, even if only a minority named it as their language of best command. In about half of the Sursilvan villages, Romansh is the language of best command of over 70% or 80%. The highest percentage is found in
Vrin with over 95%. As a daily language, it is used in nearly all municipalities by at least 70%, in about half by more than 80%, and in a third by over 90%. Overall across the Sursilvan dialect area, in the census of 2000, 70.1% named Romansh as a habitually used language, while 58.3% named it as their language of best command. == Orthography ==
