Derivation
First attested

Ultimate origin
Proto-Indo-European (*h₁p-i-)

Pronunciation

  • Classical: [ˈkoe̯p.toː][1]
  • Ecclesiastical: [ˈt͡ʃɛp.to][1]

Forms

coeptō (present infinitive coeptāre, perfect active coeptāvī, supine coeptātum); first conjugation[1]

Etymology

It is from Latin coepī (“to have begun”) + -tō, a frequentative.[2][1][3] De Vaan lists the older coepiō (“to begin”) and this verb under apīscor (“to get, reach”), which he traces to Proto-Italic *ap-(e)i- (“to get, seize”) and Proto-Indo-European *h₁p-i- (“to get, grab”), comparing Hittite epp-zi (“to take, grab”).[4]

Earliest recorded meaning

De Vaan dates it from Plautus, where someone is asked why he is setting about such a plan.[4][2]

Semantic evolution

With an infinitive it is to begin or to set about doing something: Cicero's translation of Aratus has sailors beginning to reach safe harbours, and Tacitus has an officer trying to check a mutiny.[2] With an accusative it is to venture on or attempt something, and Tacitus also uses it intransitively, of a movement of the legions beginning.[2] Lewis & Short call it mostly poetic and Tacitean, found only once in Cicero's prose.[5]

Timeline

  • c. 250–184 BC – Plautus of setting about a plan.[2][4][6]
  • 81–43 BC – Cicero in his translation of Aratus.[2][6]
  • 98–115 AD – Tacitus of beginning, trying and commencing.[2][6]
