Forms

incorrigibilis (neuter incorrigibile); third-declension two-termination adjective; comparative magis incorrigibilis[1][2]

Etymology

It is from Latin in-2 + corrigō (“to correct”), with the adjective suffix -bilis.[2][3][4] The TLL compares the rarer incorrectibilis.[2]

Earliest recorded meaning

Lewis & Short cite it from Seneca's On Anger (3.41),[1] but the TLL's earliest record is the Opus imperfectum in Matthaeum, of the 5th century, which speaks of a wickedness that is unmoved and beyond correction.[2][4]

Semantic evolution

In Late Latin it described people and faults that no correction could mend: Gregory the Great uses the comparative of the wicked, and the adverb incorrigibiliter of a fault committed so secretly that it can hardly be amended.[2] In medieval Latin it was common in church law of a cleric or canon who stayed obstinate after being rebuked,[5][6] and it also came to mean unchangeable or irrevocable.[5][4]

English took it over in the mid-14th century, from Old French or directly from Latin.[7]

Timeline

  • 5th century AD – The Opus imperfectum in Matthaeum has the earliest record the TLL gives.[2][4]
  • 540–604 AD – Gregory the Great uses the comparative and the adverb incorrigibiliter.[2][4]
  • 2nd half of the 12th century – Peter of Blois uses it.[3][6][4]
  • 1231 – An Oxford statute speaks of rebellious clerics who will not be corrected by the chancellor.[6]
  • mid-14th century – English borrows it as incorrigible.[7]

Meanings
