giving something and receiving something else in return, or switching one thing for another.
From Old French 'exchanger,' with 'ex-' meaning 'out' and 'changer' from Latin 'cambiare' (to barter). The word literally means 'to change out' or to trade.
The ability to exchange and trade is considered one of the hallmarks of human civilization—it requires trust that the other person won't cheat you, so exchange evolved alongside the concept of reputation and law.
