hype (n.)youdaoicibaDictYouDict[hype 词源字典]
"excessive or misleading publicity or advertising," 1967, American English (the verb is attested from 1937), probably in part a back-formation of hyperbole, but also from underworld slang sense "swindle by overcharging or short-changing" (1926), a back-formation of hyper "short-change con man" (1914), from prefix hyper- meaning "over, to excess." Also possibly influenced by drug addicts' slang hype, 1913 shortening of hypodermic needle. Related: Hyped; hyping. In early 18c., hyp "morbid depression of the spirits" was colloquial for hypochondria (usually as the hyp or the hyps).[hype etymology, hype origin, 英语词源]
