promiseyoudaoicibaDictYouDict[promise 词源字典]
promise: [14] Latin prōmittere originally meant simply ‘send forth’ (it was a compound verb formed from the prefix prō- ‘forward’ and mittere ‘send’, source of English mission, missile, transmit, etc). But it soon evolved metaphorically via ‘say in advance, foretell’ to ‘cause to expect’ and hence ‘promise’ – the sense adopted into English via its past participle prōmissum.
