Up to 2,500 people in central Sweden speak the language, which is the most archaic among the Dalecarlian group of languages to which it belongs, spoken in the Dalarna region of Sweden.
After the discovery that less 60 children currently speak the language, which was once banned in the mainstream Swedish school system, one preschool in Alvdalen is going to begin teaching the language to six-year-olds from September, who will go on to learn it until the age of 18.
Elfdalian contains archaic features shared with Old Norse such as verb conjugation, syllable structure, and a number of Nordic words that have been lost in standard Swedish, experts say, as well as specifically Dalecarlian or Elfdalian words and features which render the language unintelligible to outsiders.
The new policy coincides with a conference on the Elfdalian language, organized by the University of Copenhagen and taking place in the town of Alvdalen. Conference organizer Bjarne Simmelkjær Sandsgaard Hansen told the Danish newspaper Politiken newspaper that: "Elfdalian is a goldmine. It works almost like a linguistic deep freeze, where one can get a glimpse of Old Norse traits that have long since vanished in the other Nordic languages."
The initiative to teach the language in schools comes from the pressure group Ulum Dalska ['We shall speak Elfdalian'] pressure group, which has campaigned to save the language for 30 years, and also lobbies to have Elfdalian recognized as an official language in Sweden.
