What role does 成 (chéng) play in the sentence 我把十块美元换成人民币? A jukuu.com example sentence for 人民币 is:


  我把十块美元换成人民币
   I change ten dollars into Renminbi
  (Wǒ bǎ shí kuài měiyuán huàn chéng rénmínbì)


Question: What role does 成 play in the sentence 我把十块美元换成人民币?

Everything else seems to translate naturally:


我 (wǒ) = I
把 (bǎ) = take
十 (shí) = ten
块 (kuài) = pieces of
美元 (měiyuán) = US dollars
换 (huàn) = exchange
成 (chéng) = ???
人民币 (rénmínbì) = a formal way of saying Chinese yuan (Chinese money).


Dict.cn translates 成 to "succeed", etc., so it could mean something along the lines of how 了 is used.  I'm not clear on this.
成 (into) is the result complement of the verb 换(change)

换 = change
换成 = change into
兑换 = exchange
兑换成 = exchange into


兑换 mostly refers to 'currency exchange'

换 can refer to exchange between anything.



In &quot;我把十块美元换成人民币&quot; (I exchanged $10 USD into RMB), '换' is obviously short for '兑换'. You can even replace '换' with '兑' (convert) and write: &quot;我把十块美元兑成人民币&quot; (I converted $10 USD into RMB)and the meaning would still be the same.
