'exchange' originates from Old French, specifically the word 'eschanger,' where 'es-' meant 'out' and 'changer' meant 'to change.'

'eschanger' transformed into the Middle English word 'exchaunge,' and eventually became the modern English word 'exchange.'

Initially, it meant 'to change or barter,' but over time it evolved into its current meaning of 'to give and receive reciprocally.'
