Word Origin & History
from Dan. Daner (replacing O.E. Dene (pl.)); used in O.E. of Northmen generally. Perhaps ult. from a source related to O.H.G. tanar "sand bank," in reference to their homeland. Applied 1774 to a breed of large dogs. Danegeld not known by that name in O.E., or until 1086, long after the end of the Viking
depredations. Supposedly originally a tax to pay for protection from the Northmen (either to outfit defensive armies or to buy peace). Danelaw (c.1050) was the Danish law in force over that large part of England under Viking rule after c.878; the application to the land itself is modern (1837).
