Origin

This character combines a bone radical on the left with a sound component on the right. The bone radical makes sense because marrow is the soft tissue inside bones. The right side, built from characters suggesting "to have" or "possess," provides a sound hint for the pronunciation "zuI" rather than contributing to the meaning. Together, the bone classifier anchors the character to anatomy while the sound component signals how to pronounce it.
