notorious

The word notorious comes from Medieval Latin notorius, built on the classical notus, the past participle of noscere, meaning to know. Roman lawyers in the late Republic used notorius to mean something that makes itself publicly known. In Cicero's time, notus described a person or fact that was widely recognized, carrying no moral weight in either direction. The suffix -orius added agency: notorius named whatever actively brought knowledge into the open.

Medieval ecclesiastical courts adopted the term around the twelfth century because they needed a word for sins committed openly, before witnesses. A notorious crime was not necessarily wicked but was publicly verifiable, a fact no one could dispute. Thomas Aquinas used notorium in this precise legal sense, distinguishing manifest public acts from hidden ones. The word entered Old French and then Middle English by the early fifteenth century carrying this courtroom meaning: open, known to all, beyond denial.

The moral decline of the word happened slowly across the sixteenth century, when English writers began attaching it to criminals, heretics, and traitors. When someone was notorious, the public knew about them and disapproved. By 1568, when William Turner described certain bishops as notorious hypocrites, the neutral sense had all but vanished. The company a word keeps shapes what it means, and notorious kept company with villains long enough to become one.

Today the adjective clings almost entirely to disrepute, applied to swindlers, gangs, and ill-famed neighborhoods. The rapper Notorious B.I.G., born Christopher Wallace in 1972, wore the name as a wry badge, reclaiming the original Latin sense of simple renown. English preserves notoriously as an adverb meaning as everyone knows, which retains a ghost of the neutral original. In that adverb the fifteenth-century courtroom still echoes: here is a thing no one can deny.
