Etîmolojî

Inherited from Old French troquer, trochier, of unknown origin. Possibly imitative of the sound made by the hands of the exchanging parties clapping together, similar to troper (“to high five”). Or, from an unknown Germanic source.
Compare Middle English trukien (“to trade, barter”) and Medieval Latin troco (“I barter”), which could have been borrowed from the Old French verb.
