handshake
UK: ˈhændʃeɪk | US: ˈhændʃeɪk
n. a customary greeting or agreement gesture where two people clasp and shake each other's hands
n. (computing) an initial communication protocol between devices to establish connection
The word "handshake" is a transparent compound formed from "hand" (Old English hand, meaning the body part) and "shake" (Old English sceacan, meaning to move forcefully or briskly). It emerged in the early 19th century to describe the physical gesture of clasping and shaking hands, symbolizing agreement, greeting, or mutual respect. The computing sense (protocol establishment) metaphorically extends this idea of initial connection.
