query: When did the Old Norse language originate?
passage: Old Norse
The Proto-Norse language developed into Old Norse by the 8th century, and Old Norse began to develop into the modern North Germanic languages in the mid- to late 14th century, ending the language phase known as Old Norse. These dates, however, are not absolute, since written Old Norse is found well into the 15th century.[2]
passage: Norwegian language
Around 800 AD, the script was simplified to the Younger Futhark, and inscriptions became more abundant. At the same time, the beginning of the Viking Age led to the spread of Old Norse to Iceland, Greenland, and the Faroe Islands. Viking colonies also existed in parts of the British Isles, France (Normandy), and Kievan Rus. In all of these places except Iceland and the Faroes, Old Norse speakers went extinct or were absorbed into the local population.
