规范 (guīfàn) is a versatile word meaning 'standard' or 'norm' as a noun, and 'to standardize' or 'to regulate' as a verb. The character 规 (guī) originally meant 'compass'—a tool for drawing precise circles—and came to symbolize rules or guidelines; 范 (fàn) means 'model', 'pattern', or 'mold', suggesting something that sets an example or template. Together, they convey the idea of established, authoritative benchmarks that guide behavior, language use, technical processes, or social conduct.

This word appears frequently in formal, institutional, and professional contexts: education policy, workplace procedures, language teaching materials, software documentation, and government regulations. As a noun, it's often modified by adjectives like 'national', 'industry', or 'technical'; as a verb, it commonly takes an object (e.g., 规范管理 — 'standardize management') and appears in written or semi-formal speech rather than casual conversation.
