Nero comes from a Roman cognomen, a name of uncertain meaning. It could be derived from a Sabine origin meaning “strong, vigorous”, or it could be derived from a PIE root word *h₂nḗr (power, force, vital energy; man); alternatively, it could also mean “man” from the same root word. Nero is also a Finnish word meaning “genius”, an Italian word meaning “black”. Nero is also an Italian surname originating as a nickname for someone who had dark hair. Nero is also a short form of Raniero, the Italian form of Rayner, a Germanic male name meaning “advice army” composed of ragin (advice) and hari (army). Although Nero is often famously associated with the Roman emperor known for his tyranny and corruption in many people’s minds, I’ve always thought of fictional detective Nero Wolfe by Rex Stout.
