規則
きそく · kisoku · JLPT N4 · noun
rule
📏📜 規則 = standard (規) + rule (則): a standard you must follow
規 means a standard or measure, originally a compass for drawing circles. 則 means a rule or law. Two near-synonyms stacked together give the formal word for regulations. Sound hook: ki-so-ku, the key so cool it locks everyone into the rules.
