wane的词源

英文词源

wane: wane: [OE] Wane and Norwegian vana ‘spoil, waste’ are the only survivors of a family of Germanic verbs that goes back to a prehistoric *wanōjan. This was derived from the base *wan- ‘lacking’, which also produced English want. The related but now defunct English adjective wane ‘lacking’ is represented in the first syllable of wanton.
=> want, wanton
wane (v.): Old English wanian "make or become smaller gradually, diminish, decline, fade," from Proto-Germanic *wanen (cognates: Old Saxon wanon, Old Norse vana, Old Frisian wania, Middle Dutch waenen, Old High German wanon "to wane, to grow less"), from *wano- "lacking," from PIE *we-no-, from root *eue- "to leave, abandon, give out" (see vain). Related: Waned; waning; wanes.
