In Scandinavia, the term "Scandinavian languages" refers specifically to the generally mutually intelligible languages of the three continental Scandinavian countries and is thus used in a more narrow sense as a subset of the Nordic languages, leaving aside the insular subset of Faroese and Icelandic. Danish, Norwegian, and Swedish are also referred to as Scandinavian or Nordic languages, while Faroese and Icelandic are grouped together as Insular Nordic languages. The term Scandinavian arose in the 18th century as a result of the early linguistic and cultural Scandinavist movement, referring to the people, cultures, and languages of the three Scandinavian countries and stressing their common heritage.
Approximately 20 million people in the Nordic countries speak a Scandinavian language as their native language, including an approximately 5% minority in Finland. Languages belonging to the North Germanic language tree are also commonly spoken on Greenland and, to a lesser extent, by immigrants in North America.
