HunyoudaoicibaDictYouDict[Hun 词源字典]
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.[Hun etymology, Hun origin, 英语词源]
stake (n.1)youdaoicibaDictYouDict
"pointed stick or post," Old English staca "pin, stake," from Proto-Germanic *stakon (cognates: Old Norse stiaki, Danish stage, Old Frisian stake, Middle Dutch stake, Dutch staak, German stake), from PIE root *steg- (1) "pole, stick." The Germanic word has been borrowed in Spanish (estaca), Old French (estaque), and Italian stacca) and was borrowed back as attach.

Meaning "post upon which persons were bound for death by burning" is recorded from c. 1200. Meaning "vertical bar affixed to the edge of a platform of s truck, rail car, etc., to hold boards to keep the load from falling off" is from 1875; hence stake-body as a type of truck (1907). In pull up stakes, "The allusion is to pulling up the stakes of a tent" [Bartlett].
