Is Tuesday named for a one-handed god?
Old English, person from a tribe from central Asia that overran Europe in the 4c. and 5c., from Medieval Latin Hunni, apparently ultimately from Turkic Hun-yü, the name of a tribe (they were known in China as Han or Hiong-nu). Figurative sense of "reckless destroyer of beauty" is from 1806. Applied to the German in World War I by their enemies because of stories of atrocities, but the nickname originally was urged on German soldiers bound for China by Kaiser Wilhelm II in 1900, which caused a scandal.
Note: The British frequently referred to German soldiers as “Huns” during World War I and World War II as a way of emphasizing their supposed brutality.
