‘严守’ is a compound verb meaning ‘to strictly observe’ or ‘to rigorously abide by’ a rule, regulation, promise, or principle. The first character 严 (yán) means ‘strict,’ ‘severe,’ or ‘rigorous,’ while the second character 守 (shǒu) means ‘to guard,’ ‘to keep,’ or ‘to observe.’ Together, they emphasize unwavering adherence—not just following a rule, but doing so with seriousness, discipline, and consistency. It conveys a sense of responsibility and integrity.

This word is commonly used in formal, professional, or moral contexts: workplace regulations, military discipline, ethical codes, exam rules, or personal commitments. It often appears with objects like 规定 (regulations), 纪律 (discipline), 承诺 (promises), or 原则 (principles). While it can describe individual behavior, it’s also frequently used in institutional or collective settings—e.g., teachers, soldiers, or officials are expected to 严守 their duties. It carries a slightly solemn, respectful tone and is rarely used in casual speech.
