The word "exchange" originates from Old French eschangier, derived from Latin excambiare (ex- "out" + cambiare "to swap"). The root cambiare evolved into "change" in English, retaining the core idea of alteration or substitution. The prefix ex- emphasizes the outward or reciprocal nature of the action. Over time, "exchange" broadened from physical bartering to abstract trades (e.g., ideas, currencies).
