Pronunciation

  • Classical: [ɪmˈpuː.nɪs][1]
  • Ecclesiastical: [imˈpuː.nis][1]

Forms

impūnis (neuter impūne, adverb impūnē); third-declension two-termination adjective[1]

Etymology

It is a back-formation from Latin impūne (“without punishment”).[2][3] The adverb is formed with in- (“not”) and poena (“penalty”).[4][5]

Earliest recorded meaning

Apuleius uses it in the Metamorphoses of someone who expects to go not only unpunished but even praised.[3][6]

Semantic evolution

The adjective is very rare and perhaps only post-classical, while the adverb impūne was frequent and classical.[4] A second instance in Solinus is doubtful, since Mommsen reads immūnis there.[4][3] English borrowed it in the 1610s as impune “unpunished”, now obsolete.[7]

Timeline

  • c. 125–175 AD – Apuleius uses it in the Metamorphoses.[3][5]
  • first half of the 3rd century AD – A doubtful reading in Solinus.[4][5]
  • 1610s – English impune “unpunished” is taken from it.[7]

Meanings
