purposeyoudaoicibaDictYouDict[purpose 词源字典]
purpose: [13] Purpose, propose [14], and propound [16] are ultimately the same word. All go back to Latin prōpōnere ‘put forward, declare’, a compound verb formed from the prefix prō- ‘forward’ and pōnere ‘place’ (source of English pose, position, etc). Its past participle prōpositus was the source of two distinct Old French verbs: the minimally altered proposer, source of English propose; and purposer, which contains the Old French descendant of the Latin prefix prō-, source of English purpose. Propound is an alteration of an earlier propone (source of proponent [16]), which was based directly on prōpōnere.
