A wrestling or martial arts hold in which one fighter controls an opponent's arm by bending or locking it.
Compound noun from 'arm' and 'lock', describing a grappling technique that physically restricts arm movement. Used in combat sports since at least the 19th century.
Martial arts terminology often uses simple compound words—'armlock,' 'headlock,' 'leglock'—that vividly describe the technique by naming exactly what body part is being locked and how, making them intuitive even to beginners.
