exchange

exchange: [14] Like change, exchange comes ultimately from Latin cambīre ‘barter’. In postclassical times this had the prefix ex- added to it, here functioning as an indicator of ‘change’, producing late Latin *excambiāre. In Old French this became eschangier (whence modern French échanger), which English acquired via Anglo- Norman eschaunge. A 15th-century reversion to the original Latin spelling of the prefix produced modern English exchange.

Practice of merchants or lenders meeting to exchange bills of debt led to meaning "building for mercantile business" (1580s).
