English 'Denmark' comes from Old Norse Danmǫrk, meaning 'borderland of the Danes' — the tribal name may refer to their flat terrain, while 'mark' (border) is the same word found in 'march' and 'marquis'.
A Nordic country in Northern Europe, the southernmost of the Scandinavian countries.
English 'Denmark' derives from Old Norse 'Danmǫrk', a compound of 'Danir' (the Danes) and 'mǫrk' (border-land, march, forest). The tribal name 'Dane' (Old Norse 'Danir') is of uncertain origin — proposals include a connection to Proto-Germanic *dan- meaning 'low, flat land' (Denmark is notably flat) or to a word meaning 'woodland' (compare 'den' as in an animal's den).

The English words 'Danegeld' (tribute paid to Viking raiders) and 'Danelaw' (the area of England under Danish law) preserve the impact of Danish Vikings on English history. The 'mark' in Denmark is the same word as in 'march' (border region) and 'marquis' (ruler of a border region) — all from PIE *merǵ- meaning 'edge'.
