‘纪律’ (jì lǜ) is a compound noun meaning ‘discipline’ or ‘code of conduct’. The first character 纪 (jì) originally meant ‘to record’ or ‘to regulate’, and in modern usage conveys the idea of order, rules, or standards. The second character 律 (lǜ) means ‘law’, ‘regulation’, or ‘principle’, emphasizing formal, binding rules. Together, 纪律 refers to the established rules—formal or informal—that govern behavior in groups, institutions, or personal life. It carries a strong sense of responsibility, accountability, and collective expectation.

This word is commonly used in educational, military, workplace, and party-political contexts in Chinese society. It often implies not just obedience but internalized commitment to shared values. Unlike the English word ‘discipline’, which can also mean self-control or training, 纪律 focuses more on externally defined, socially enforced norms. It frequently appears in phrases like 遵守纪律 (zūnshǒu jìlǜ, ‘to obey discipline’) or 违反纪律 (wéifǎn jìlǜ, ‘to violate discipline’), highlighting its normative and evaluative function.
