“The term ‘Norse’ is used to describe the various peoples of Scandinavia who spoke the Old Norse language between the eighth and thirteenth centuries AD. While it had eastern and western dialects it would have been generally mutually understood across the range of areas within which it was spoken. A third recognisable form was spoken on the island of Gotland.
The Old Norse language later developed into modern Danish, Faroese, Icelandic, Norwegian and Swedish. In addition, there once existed the so-called Norn languages of Orkney and Shetland that are now extinct. It was, essentially, the language of the Vikings.”
