yieldyoudaoicibaDictgodict[yield 词源字典]
yield: [OE] Yield is descended from prehistoric Germanic *gelthan ‘pay’, which also produced German gelten ‘pay’ (German geld ‘money’ comes from the same base). It originally meant ‘pay’ in English too, and it seems the sense ‘surrender’, which emerged in the 13th century, may be due to the influence of French rendre ‘give’, which is used reflexively for ‘surrender’.
[yield etymology, yield origin, 英语词源]
yield (v.)youdaoicibaDictgodict
Old English gieldan (West Saxon), geldan (Anglian) "to pay, pay for; reward, render; worship, serve, sacrifice to" (class III strong verb; past tense geald, past participle golden), from Proto-Germanic *geldan "pay" (cognates: Old Saxon geldan "to be worth," Old Norse gjaldo "to repay, return," Middle Dutch ghelden, Dutch gelden "to cost, be worth, concern," Old High German geltan, German gelten "to be worth," Gothic fra-gildan "to repay, requite"). This is from PIE *gheldh- "to pay," a root found only in Balto-Slavic and Germanic (and Old Church Slavonic žledo, Lithuanian geliuoti might be Germanic loan-words).

"[T]he only generally surviving senses on the Continent are 'to be worth; to be valid, to concern, apply to,' which are not represented at all in the English word" [OED]; sense development in English comes via use of this word to translate Latin reddere, French rendre. Sense of "give in return for labor or capital invested" is from early 14c. Intransitive sense of "give oneself up, submit, surrender (to a foe)" is from c. 1300. Related to Middle Low German and Middle Dutch gelt, Dutch geld, German Geld "money." Related: Yielded; yielding.
