īnsōns (genitive īnsontis); third-declension one-termination adjective[1]
Etymology
It is from in- (“not”) and sōns “guilty”.[2][1][3] De Vaan traces ⟨sōns⟩ to Proto-Italic ⟨*sont-⟩ “being”, the old participle of “to be”, Proto-Indo-European *h₁s-ónt-s (“existing, real”), cognate with Sanskrit सत् (sánt-, “being, real”) and Ancient Greek ὤν (ṓn, “being”).[4]
Earliest recorded meaning
The OLD's earliest citation is Plautus, “innocent”.[2] Köbler dates Plautus c. 250–184 BC.[3]
Semantic evolution
It meant guiltless, innocent, as in Plautus and in īnsontem probrī accūsāre “to accuse someone innocent of a disgrace”, and in poetry harmless, doing no injury, as in Horace, and Lewis & Short note that it is classical but not used by Cicero or Caesar.[2][5]
In Ecclesiastical Latin it means innocent.[6] British Medieval Latin used it also as a noun for an innocent person.[7]
