swap的词源
英文词源
- swap
- swap: [14] Swap originally meant ‘hit’ (‘With a swing of his sword [he] swapped him in the face’, Destruction of Troy 1400). It came from a prehistoric Germanic base denoting ‘hit’ (presumably imitative of the sound of hitting), which also produced German schwappen ‘splash, whack’. The modern English sense ‘exchange’ emerged in the 16th century from the notion of ‘striking the hands together to seal a bargain’.
- swap (v.)
- c. 1200, "to strike, strike the hands together," of uncertain origin, possibly imitative of the sound of hitting or slapping. The sense of "to exchange, barter, trade" is first recorded 1590s, possibly from the notion of slapping hands together as a sign of agreement in bargaining (as in strike a bargain). Related: Swapped; swapping. The noun in this sense is attested from 1620s; earlier "a striking, an act of striking" (mid-13c.). Swap-meet attested from 1968, American English.

该词从中世纪英语swappen（击，击掌）演变而来。按旧时商业习俗，交易般方达成协议时，常阻击掌或握手来表示，故有strike hands．strike a bargain等说法。这种（击掌）成交方式与拍卖中的拍板成交有点类似swap的今义“交换”、“做交易”即源出这一习俗。swap亦可拼作swop。
