Forms
innoxius (feminine innoxia, neuter innoxium); first/second-declension adjective[1] The comparative innoxiior occurs only in a speech of Cato.[2]
Etymology
It is formed from the negative prefix in- (“not”) and noxius (“harmful, guilty”).[2][3] De Vaan derives ⟨noxius⟩ from noxa (“harm, offence”), perhaps as a back-formation from obnoxius, and both from noceō (“to harm”), which goes back to Proto-Italic *nokeje- (“to cause death”) and Proto-Indo-European *noḱ-eie- (“to make disappear, cause death”).[4]
Earliest recorded meaning
Köbler dates it from Plautus,[3] where a man complains of being mocked though he is poor and innocent.[2]
Semantic evolution
It is blameless or innocent, of people, also with an ablative or genitive of an offence, as Tacitus' innocent age of children, and of actions not accompanied by crime or malice.[2] Actively it is harmless or innocuous, as Virgil's words that were not harmless, Pliny's animals harmless to the natives, and Virgil's harmless snake.[2][5] Passively it is unharmed or safe, and unpunished, as Sallust's men who lived unharmed and flourishing without fear.[2][1]
In medieval Latin it is “not bound”.[6]
