Forms

approbātiō f (genitive approbātiōnis); third declension[1] Also spelled adprobātiō.[2][3]

Etymology

It is from Latin approbō (“to approve, commend”) + -tiō.[2][1] That verb is formed from ad- and probō (“to approve, prove”),[4][5] which de Vaan derives from probus (“good, honest”).[5]

Earliest recorded meaning

Its earliest example in the TLL is in Cicero's De inventione, where the approval or offence of people (hominum aut adprobātiō aut offēnsiō) is weighed.[6][7]

Semantic evolution

Most of its classical uses are Cicero's: the approval of an audience, the people or the senate.[3][6] In Cicero's philosophical works it renders the Stoic term for the mind's assent to what it perceives, which the Greeks called synkatathesis, and it can also mean a settled decision.[2][8] In rhetoric it is the proof that confirms a suspicion or a premise.[2][9]

Ecclesiastical Latin used it for approval and sanction.[10] English approbation (early 15th century) comes from it, partly through Old French.[4]

Timeline

  • 81–43 BC – Cicero uses it for the approval of hearers and for philosophical assent.[2][6][7]
  • 59 BC–AD 17 – Livy uses it of the approval of the senate.[6][7]
  • early 15th century – English borrows it as approbation.[4]
