About

耐 is a phono-semantic compound with 而 on the left, originally depicting a beard but serving as the phonetic component, and 寸 on the right, meaning a rule or hand action. Its etymology traces to an ancient punishment of shaving a beard, requiring the person to bear humiliation and consequence. From this context, the meaning broadened to enduring hardship, bearing pain, and showing patience. Today, it describes both durable materials and people with stamina.
