Frisian

Member of a Germanic people of northwestern Europe (Friesland and the Frisian Islands). In Roman times they occupied the coast of Holland and may have taken part in the Anglo-Saxon invasions of Britain. Their language is closely akin to Anglo-Saxon, with which it forms the Anglo-Frisian branch of the West Germanic languages, part of the Indo-European family.

The Frisian language is almost extinct in the German districts of East Friesland, but it has attained some literary importance in the North Frisian Islands and Schleswig and developed a considerable literature in the West Frisian dialect of the Dutch province of Friesland.
