Pronunciation

  • Classical: [deː.fɪ.kiˈɛn.ti.a][1]
  • Ecclesiastical: [de.fi.t͡ʃiˈɛn.t͡si.a][1]

Forms

dēficientia f (genitive dēficientiae); first declension[1]

Etymology

It is formed from Latin dēficiēns + -ia, from the present participle of dēficiō (“to fail, be lacking”).[1][2]

Earliest recorded meaning

The TLL's first record is the Ars rhetorica of Fortunatianus, where it is the rhetorical term for ellipsis, one of the ways in which ambiguity arises.[2][3]

Semantic evolution

Paulinus of Nola uses it for a want or weakening.[4][5] In medieval philosophy it is an imperfection or defect;[6] Thomas Aquinas uses it for a ceasing or falling away and as a synonym of defectus, opposed to indeficientia.[7] The MLW also records the senses loss, delay, and end or end point.[6] Regional sources have it for a shortfall (Hungary, 1423),[8] for feebleness and for the desertion of someone (Poland).[9] Italian deficienza comes from it.[3]

Timeline

  • 4th century AD – Fortunatianus uses it for ellipsis;[2][3][10] Köbler dates him with a query.[2][3][10]
  • c. 353–431 AD – Paulinus of Nola uses it for a want.[4][5][10]
  • 1423 – A Hungarian record uses it for a shortfall.[8]
  • 1455 – A Polish text uses it for feebleness.[9]
