Pronunciation

  • Classical: [ɪm.pɛˈtraː.bɪ.lɪs][1]
  • Ecclesiastical: [im.peˈtraː.bi.lis][1]

Forms

impetrābilis (neuter impetrābile); third-declension two-termination adjective[1]

Etymology

It is from Latin impetrō (“to obtain by request”) + -bilis.[2][3][1] De Vaan takes impetrō to contain patrō (“to accomplish”), a verb made from pater (“father”).[4]

Earliest recorded meaning

It is found from Plautus on,[3] first in an active sense, “good at getting what one asks”: in the Mercator a character says that nobody alive is better at getting his way (impetrabilior qui vivat nullus est), and in the Mostellaria one says that no envoy more likely to win him over could have come.[2][3][5]

Semantic evolution

The passive sense, “easy to obtain”, appears in Livy, who speaks of a peace that would be easier to get, and in Tacitus of pardon.[2][5][6] Propertius has a vow that wins its request, and Plautus a lucky day.[6] Ammianus calls a ruler successful in carrying out his plans impetrabilis.[5] An inscription is dedicated to Hercules inpetrabilis.[3]

In medieval Latin it meant “obtainable by prayer or request”,[7] and in British sources also what could be obtained in a court.[8]

Timeline

  • c. 250–184 BC – Plautus uses it of people who get what they ask.[2][3][9]
  • 57/46–12 BC – Propertius uses it of a vow.[10][6][9]
  • 59 BC–AD 17 – Livy uses it in the sense “easy to obtain”.[2][9]
  • c. 390 AD – Ammianus uses it of a successful ruler.[5][9]
  • 1279 – A letter of Peckham uses it of what could be obtained at the Roman curia.[8]
