How it's used

Refers specifically to the hinge-like movement of the lower jaw, often used in contexts involving excessive talking or physical discomfort. It is frequently paired with verbs like 軟 or 痛 to describe fatigue or pain after prolonged activity. The term captures the mechanical sense of the jaw joint rather than just the jawbone itself.

Common mistake

Do not confuse this with 下巴, which refers to the chin or the jaw area in a more general sense. 牙鉸 specifically highlights the joint or the action of the jaw moving.
