肢

It is a phono-semantic compound, composed of:

肉 (⺼, “flesh”) – semantic element, indicating body or flesh.

支 (ji, “to support, to branch”) – phonetic element.

Thus, 肢 literally refers to the flesh-branches of the body - arms and legs.

肢 is a straightforward anatomical character, denoting the arms and legs as the body’s extensions, and remains widely used in medical, anatomical, and descriptive vocabulary across East Asia.

사지 (四肢) – the four limbs

지체 (肢體) – body, limbs; also metaphorically “delay” (by semantic extension of 體)

상지 (上肢) – upper limb (arm)

하지 (下肢) – lower limb (leg)
