socket
UK: ˈsɒkɪt | US: ˈsɑːkɪt
n. a hollow or cavity into which something fits or is inserted (e.g., an electrical socket)
n. (anatomy) the bony part of the skull that holds the eye (eye socket)
vt. to place or fix into a socket
The word "socket" originates from Middle English soket, derived from Old French socquet (a small plowshare), which itself came from soc (plowshare). The term evolved to describe a "hollow fitting" due to the resemblance of a plowshare's shape to a cavity. The diminutive suffix -et (from Old French) reinforces the idea of a small or specialized opening. Over time, "socket" generalized to any hollow structure designed to hold another object securely, such as electrical sockets or anatomical joints.
