Definition of North germanic languages

The North Germanic languages make up one of the three branches of the Germanic languages, a sub-family of the Indo-European languages, along with the West Germanic languages  and the East Germanic languages. Derived from Proto-Norse and Old Norse, they are spoken in Denmark, Norway, Sweden, the Faroe Islands, Iceland and (to some extent) Greenland, as well as by a significant Swedish minority in Finland and by immigrant groups mainly in North America and Australia. The language group is often called either Scandinavian or, today, less frequently in the English language, Nordic languages. The latter term is a direct translation from "nordiska språk", most commonly used by both scholars and laymen in the Nordic countries and is often favored by these when writing in English.
