found: Wikipedia, May 31, 2011("Norn is an Indo-European language belonging to the North Germanic branch of the Germanic languages. Together with Faroese, Icelandic, and Norwegian it belongs to the West Scandinavian group, separating it from the East Scandinavian group consisting of Swedish and Danish [...] Norn is generally considered to have been fairly similar to Faroese, sharing many phonological and grammatical traits with this language, and might even have been mutually intelligible with it; thus, it can be considered an insular Scandinavian language.")
