骸

Phono-semantic compound:

骨 (bone) — semantic component

亥 (pronounced hài) — phonetic component, giving the sound (hae / hái / gai)

Thus the meaning is “something related to bone,” narrowing into:

- skeletal frame

- bodily remains

- bones of a corpse (as in 骸骨)

Modern Korean generally uses 骸 only in academic, medical, or literary contexts.

해골 (骸骨) — skull, skeleton

해체 (骸滯) — obstruction of bodily movement (rare / literary)

해령 (骸靈) — spirit remaining in bones (rare)

Often interchangeable in meaning with 骨, but 骸 specifically implies the skeletal remains of a person, often with emotional or solemn nuance.

In classical philosophy (especially Zhuangzi), 形骸 (“body and bones”) appears in discussions about the physical self versus the spiritual self.

The character is common in funerary inscriptions, archaeology, and traditional medicine.

Classical citations:

《文選》 (Wen Xuan)

「形骸已弊。」

“My body and bones are already worn and exhausted.”

《莊子》 (Zhuang Zhou)

「形骸之外，吾無所求。」

“Beyond this body and bones, I have nothing I seek.”
