Norway was originally called Nordweg, meaning the “Northern Way.” The name Norway comes from the Old English word Norþweg mentioned in 880, meaning “northern way” or “way leading to the north”, which is how the Anglo-Saxons referred to the coastline of atlantic Norway. The Anglo-Saxons of Britain also referred to the kingdom of Norway in 880 as Norðmanna land.
