What 羸 means
Thin, frail, or worn out.
羸兵 means weakened troops; older uses also describe frail people and shabby objects. 羸其角 uses 羸 for “entangle,” a classical loan linked to 纍 and 虆. Qin bamboo writing slips attest an early form from the late Warring States. The Han-era dictionary Shuowen assigns 羊 the meaning role and 𣎆 the sound.
