Etymology: The word "exchange" carries an unexpected spelling story. Its Old French ancestor was "eschange," and English spelled it that way for centuries. The modern spelling with "x" arrived later, when writers adjusted it to match the Latin prefix "ex-," which they took to be part of the word. The pronunciation then shifted to follow the new look, so the sound we hear today was influenced by a spelling change rather than the other way around. Underneath is a Latin idea of swapping. Late Latin speakers built "excambiare" from "ex-" (out, away) and "cambire," a form linked to "cambiō," meaning to barter or change money. The notion was originally about moving goods or currency from one hand to another. Old French turned it into "eschanger," and that verb came into Middle English as "eschaungen," gradually pushing out the native Old English word "wrixlan," meaning to change or reciprocate. "Wrixle" survives as one of that older word's descendants, a reminder of the vocabulary English lost.
