Origin

From Middle English eschaunge, borrowed from Anglo-Norman eschaunge, from Old French eschange (whence modern French échange), from the verb eschanger, from Vulgar Latin *excambiāre (from Latin ex with Late Latin cambiō). Spelling later changed on the basis of ex-, with pronunciation following. By surface analysis, ex- + change.
