Jamtlandic or
Jamtish (
jamska ) is a Group of
dialects spoken in the
Swedish province of
Jämtland. It is commonly used in the region between the modern Swedish–
Norwegian border in the west and the pre-1645 Swedish-Norwegian border in the east, though
Trøndersk is spoken in Frostviken in the northernmost part of Jämtland colonized in the 18th century by Norwegians, and
Norrlandic is spoken in
Ragunda in the easternmost part of Jämtland which until the 13th century was a part of
Ångermanland.
