Insular Scots

Both dialects share much Norn vocabulary, Shetlandic more so, than does any other Scots dialect, perhaps because they both were under strong Norwegian influence in their recent past. In ancient times, Pictish was spoken in the islands. Then the Vikings invaded and settled, establishing the Norn language there. Although the islands thereafter owed allegiance to Norway, they became involved politically with Scotland. Scotland annexed the islands in 1472; by then, Scots was spoken.

It should not be confused with the vernacular of the Islands of the Clyde.
