Where does handshake come from?
“Handshake” is an English compound formed from “hand” and “shake.” “Hand” descends from Old English “hand,” while “shake” descends from Old English “sceccan,” meaning to move or shake something sharply. The compound developed from the literal practice of clasping and shaking hands as a greeting or pledge, and it later acquired the figurative sense of an agreement.
