Modern Gutnish, or Gotlandic, is the native language of the Gotlandic people on the island of Gotland in present-day Sweden. It was both a spoken and written language until late medieval times. Today it exists as a spoken language, but is to some degree mixed with Swedish, Danish and German. It is an open issue whether modern Gutnish is to be considered an independent language or a Scandinavian dialect. It derives, however, from Old Gutnish.
Knowledge of Gutnish is relatively weak both among Gotlanders (Gutes) and other Swedes. It is spoken mainly in the southern parts of the island and in some parts of Fårö. Gutnish exists in two variants, Mainland Gutnish and Faroymal on Fårö. The Faroymal is considered the more archaic of the two forms.
Some features of Gutnish include the preservation of Old Norse diphthongs like ai in for instance stain (Swedish sten, English stone) and oy in for example doy (Swedish dö, English die). There is also a triphthong that exists in no other Norse languages: iau as in skiaute/skiauta (Swedish skjuta, English shoot).
