The word "chocks" originated from the Middle English term "chok", which meant "block" or "log". This Middle English word was derived from the Old English word "ceoc", meaning "cheek" or "jaw". Over time, "chock" came to refer specifically to a solid block or wedge used to prevent the movement of a wheel, vehicle, or object. These chocks were typically made of wood or sometimes metal and were positioned in front of or behind a wheel to keep it from rolling. As language evolved, the plural form "chocks" emerged to denote multiple such blocks or wedges.
