Modern English
swap

Before swap meant trading baseball cards or houses, it was a little physical: Middle English swappen could mean “to strike” or “to hurl.” The exchange sense may have grown from the old ritual of striking or slapping hands to seal a bargain—the medieval equivalent of saying, “Done.” But the ancestry is foggy: some evidence points toward Old English *swappian, “to swoop,” while German schwappen, “to slosh,” suggests a broader family of vivid Germanic sound-and-motion words. By the 1590s, the word had completed its curious journey from blow to bargain, turning a smack of the hands into a trade. So every time you say “Let’s swap,” you may be echoing an ancient handshake whose verbal ancestry began with something hitting something else.
