The word 偏执 (piānzhí) is a modern Chinese compound formed by combining two meaningful characters: 偏 (piān), which conveys "biased", "one-sided", or "partial", and 执 (zhí), which means "to hold onto", "to persist in", or "to be stubborn". Together, they create a semantic fusion where 偏 modifies the nature of the 执, resulting in the meaning of stubbornly adhering to a one-sided, irrational belief or viewpoint. This term is often used in psychological or clinical contexts to translate concepts like "paranoid" or "obsessive", as in 偏执型人格障碍 (piānzhí xíng réngé zhàng'ài) or "paranoid personality disorder", capturing the essence of a fixed, distorted, and unshakeable conviction.
