Pronunciation

  • Classical: [ɪm.pɔs.sɪˈbɪ.lɪ.taːs][1]
  • Ecclesiastical: [im.pos.siˈbiː.li.tas][1]

Forms

impossibilitās f (genitive impossibilitātis); third declension[1] Also spelled inpossibilitās.[2][1]

Etymology

It is from Latin impossibilis (“impossible”) + -tās,[2][1] itself formed from possibilis (“possible”), from possum (“to be able”).[1]

Earliest recorded meaning

Apuleius, in the Metamorphoses, has Psyche turned to stone by the impossibility of her task.[2][3]

Semantic evolution

Lewis and Short call it post-classical; after Apuleius it is found in Tertullian's treatise on baptism.[4][5]

In medieval Latin it meant both impossibility, or a thing that cannot be done,[6][7] and a person's inability or incapacity to do something, weakness.[8][6][9] Conte gives this Late Latin word as the source of Italian impossibilità,[10] and it has descendants in the other Romance languages too, such as French impossibilité and Spanish imposibilidad.[1]

Timeline

  • c. 125–175 AD – Apuleius uses it of Psyche's impossible task.[2][3]
  • c. 160–220 AD – Tertullian uses it in his treatise on baptism.[4][5][3]

Meanings

Noun

  1. Impossibility.[2][4]
