About
The character 膂 (lǚ) is a phono-semantic compound structured vertically. The upper component 旅 (lǚ) provides the pronunciation, while the lower radical 月 (ròu), meaning flesh, indicates it relates to anatomy. It primarily denotes the spine or the surrounding musculature. In classical and medical texts, it often signifies core physical strength or the body's central support structure, forming a precise term for the dorsal region and its associated fortitude.
