Exchanger → It is formed from "ex-" (meaning out of or from) and "changere" (from Old French, meaning to change). The word "exchanger" refers to a person who changes or swaps something, typically in a financial context.
Think of someone who takes something 'out' ('ex-') and 'changes' it for something else — that's what an exchanger does.
