Etymology

The word "keypad" is a compound of "key" (from Old English cǣg, meaning "device for locking/unlocking" or "button for input") and "pad" (from Low German pad, meaning "sole of the foot" or later "flat surface"). The term emerged in the mid-20th century with the rise of electronic devices, combining the concept of input keys ("key") arranged on a compact surface ("pad"). This reflects the functional design of early telephone and calculator interfaces.
