Origin & History of “swap”
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’.
