Forms
incorruptus (feminine incorrupta, neuter incorruptum, comparative incorruptior); first/second-declension adjective[1] It is also spelled inconrupt-.[2] The comparative and superlative are used from Cicero on.[3][4]
Etymology
It is formed from the negative prefix in- (“not”) and corruptus (“spoiled”), the participle of corrumpō (“to spoil, corrupt”).[4][3] De Vaan traces ⟨rumpō⟩, the base of that verb, to Proto-Italic *ru-n-p- (“to break”) and Proto-Indo-European *Hru-n-p- (“to break”), cognate with Old English rēofan (“to break, tear”).[5]
Earliest recorded meaning
Köbler's first source is Cicero;[6] Lucretius writes that some believe heaven and earth will remain undamaged.[4]
Semantic evolution
It is “undamaged, unspoilt”, and also proof against decay, as Sallust's imperishable mind.[4] Of water and the like it is pure, uncontaminated, as Curtius' river Cydnus, and of documents genuine, not tampered with.[4] Morally it is “uncorrupted, pure”: Cicero says the gods should be worshipped with a pure mind and voice.[4] Of persons and judgements it means unbribed, impartial, as Cicero's question “what could be more upright, more incorruptible than this inquiry?”[4]
Church Latin glosses it “incorrupted”.[7]
