不遵 is a formal, written verb meaning 'to disobey' or 'to flout', especially in relation to rules, laws, orders, or established norms. The first character 不 (bù) is the standard negation prefix, while 遵 (zūn) means 'to obey', 'to comply with', or 'to follow' — as in 遵守 (zūnshǒu, 'to abide by'). Together, they form a compact, two-character compound that conveys deliberate noncompliance, often with a tone of seriousness or criticism.

This word appears frequently in official documents, news reports, legal contexts, and formal speeches — rarely in casual conversation. It implies conscious refusal rather than accidental neglect, and typically carries negative moral or institutional judgment. While grammatically it functions like a transitive verb, it is almost always followed by an object such as 法律 (fǎlǜ, 'law'), 规定 (guīdìng, 'regulation'), or 上级指示 (shàngjí zhǐshì, 'superior’s instructions').
