Origin & History of “rule”
Rule is one of a largish family of English words that go back ultimately to Latin rēgula ‘straight stick, ruler, rule, pattern’ (whose close relatives rēx ‘king’ and regere ‘rule’ have also contributed royally to English vocabulary in the form of rector, regent, regiment, royal, etc). Derivatives have produced regular and regulate, while rēgula itself has given rail ‘bar’ and, via vulgar Latin *regula and Old French reule, rule.
