This word began life as a plain old spotlight, not a warning siren. In medieval Latin, nōtōrius simply meant “well-known,” the verbal equivalent of everybody in town having heard your name by supper. But English speakers kept finding it next to words like thief, liar, and scandal, and by the 1600s the shine had gone sour. That’s the same ancient know-root behind notice, notable, and knowledge, so notorious is basically the overexposed cousin who showed up to the family reunion and left with a reputation. By the time the word reached modern English, it no longer meant merely famous — it meant famous in the way a smashed window is famous: impossible to ignore, and not for the right reasons.
