IPA: //ˈhændʃeɪk//
KK: /ˈhændʃeɪk/
A greeting or farewell gesture where two people grasp each other's hands and often shake them up and down.
They sealed their agreement with a firm handshake.
Handshake → It is formed from "hand" (from Old English "hand", meaning the end part of the arm) and "shake" (from Old English "sceacan", meaning to move back and forth). The word "handshake" refers to the act of moving hands back and forth, typically as a greeting or agreement.
Think of using your 'hand' to 'shake' someone else's hand — that's how a handshake is a greeting or agreement.
