Old Norse is classical North Germanic language used from roughly 1150 to 1350. Its predecessor is Old Scandinavian, from which West Scandinavian (later known as Old Norse) and East Scandinavian developed (C.f. Runic Swedish).
Old Norse is the literary language of the Icelandic sagas, skaldic poems, and Eddas. The term Old Norse embraces Old Norwegian as well as Old Icelandic
Grammatically, the Old Norse language remained remarkably stable for 200 years. Verbs were inflected for tense, mood, person, and number. Old Norse is the parent language of the three modern languages, Icelandic, Faroese, and Norwegian, and one extinct language called Norn.Literature sources
