Confidence
Established
Formation
Derivation
First attested
Pomponius (Atellan farce)
Ultimate origin
Proto-Indo-European (*h₁ep-)

Pronunciation

  • Classical: [ˈap.toː][1]
  • Ecclesiastical: [ˈap.to][1]

Forms

aptō (present infinitive aptāre, perfect active aptāvī, supine aptātum); first conjugation[1]

Etymology

It is formed from aptus (“fastened, fitting”) with the suffix -tō,[2][1] or from apiō (“to fasten”), as the TLL and Lewis and Short have it.[3][4] De Vaan takes ⟨apiō⟩ and ⟨aptus⟩ with apīscor (“to seize, obtain”), from Proto-Italic *apei- (“to get, seize”) and Proto-Indo-European *h₁p-i- (“to get, grab”), cognate with Hittite eppzi (“takes”) and Sanskrit आप (ā́pa, “has reached”).[5]

Earliest recorded meaning

Its first example in the OLD is the Atellan farce of Pomponius: “prepare the feast generously, boys”.[2]

Semantic evolution

It is to put something in position, fit or fix it, as Virgil's ash stakes in a vineyard, and to put on armour or ornaments, as Livy's soldiers who formed ranks with their arms scarcely fitted on.[2] It is to make ready for use, as Virgil's Turnus fitting sword and shield, and to apply words, as Quintilian's proverbs aptly used.[2] Petronius has a silver skeleton fitted together so that its joints could bend.[2]

It is also to prepare or equip, as Virgil's fleet fitted with sails, and to adapt or accommodate, as Horace's wars of Numantia not to be fitted to the lyre, and to attune the mind.[2][4] Church Latin glosses it “prepare, adapt, fit, adjust”.[6]

Timeline

  • 70–19 BC – Virgil of fitting and equipping.[2][7]
  • 65–8 BC – Horace of adapting to the lyre.[2][7]
  • 59 BC–17 AD – Livy of putting on armour.[2][7]
