Old Scandinavian (Old Norse) language
 
The ancestor of all modern Scandinavian languages, Old Scandinavian was a branch of the Common Germanic language spoken by those who migrated north from Central Europe, to the Jutland peninsula and southern Scandinavia. The most ancient inscriptions in Old Norse refer to the 3rd and the 5th century centuries AD. They were short signs written by the runic alphabet, which had 24 letters and spread among Germanic tribes until they picked up the Latin alphabet.

In the 9th language Old Norse speakers began their migrations through the whole Europe, started to be called Vikings, and therefore the language dialect varieties grew stronger until two separate languages appeared: Western Scandinavian, the ancestor of Norwegian, Icelandic and Faroese, and Eastern Scandinavian, the father-tongue of Danish and Swedish.

The most common features of the North Germanic and Old Norse languages were, for example, the passive vocie ending in -s, an enclitic form of the defonite article and some other.

Many Old Norse words were borrowed by English, Scots, nad even Russian, due to vast scales of Viking migrations in the Middle Ages.
