绝世 is a classical compound with two main literary meanings: 'peerless, unmatched in one's generation' (e.g., 绝世美女) and 'without posterity, heirless' (referring to the end of a family line). The source POS is 'v.o.', but the word is not commonly used as a separable verb in modern Chinese; it functions primarily as an adjective or noun. The gloss also lists 'die', which is a rare, archaic sense. The POS label likely needs correction.
