anti-lock

The term "anti-lock" is a modern compound formed from two distinct linguistic elements. The prefix "anti-" originates from the Greek preposition antí, meaning "against," which entered English through Latin and French. The word "lock" derives from the Old English loc, referring to a fastening or mechanism that secures something in place. In automotive engineering, "lock" metaphorically describes the wheels ceasing to rotate and skidding. Therefore, "anti-lock" logically constructs a meaning of "against locking," directly describing a system designed to counteract the dangerous locking of vehicle brakes, a concept fully realized in the late 20th century with the advent of electronic anti-lock braking systems (ABS).

Structure: anti (against) + lock (fasten, seize) - anti: From Greek, via Latin and French. A prefix meaning "against," "opposite of," or "preventative of." - lock: From Old English loc, meaning "a fastening, enclosure, or barrier." In this context, it refers to the seizing or jamming of a mechanical part.
