Forms
coepiō (present infinitive coepere, perfect active coepī, supine coeptum); third (-iō variant) conjugation[1] Normally only the perfect stem is used: coepī, coepisse, coeptum.[2][3] Present-stem forms (coepiam, coepiat, coepere) appear in Plautus, Cato, Caecilius and Terence.[2] In Plautus and Lucretius coēpī is sometimes trisyllabic.[2] The future participle coeptūrus is used by Livy, Quintilian, Pliny and Suetonius.[3] The present coepiō with a full conjugation is a post-classical back-formation from coepī.[1]
Etymology
It is formed from Latin co- + apiō (“to fasten, tie”), “to lay hold of”; the present ⟨coepiō⟩ is a rare early form beside the common perfect ⟨coepī⟩.[2][1][4] The perfect goes back to ⟨*co-ēpī⟩, with the long-vowel perfect of Proto-Indo-European *h₁e-h₁p-, contracted, or it was influenced by the participle ⟨coeptus⟩ from ⟨*ko-aptos⟩.[4]
The simple verbs apīscor “to seize, obtain” and apiō continue Proto-Italic *ap-(e)i- (“to get, seize”), from Proto-Indo-European *h₁p-i- (“to get, grab”); compare Hittite epp- (“to take, grab”) and Sanskrit आप (ā́pa, “has reached”).[4]
Earliest recorded meaning
Ennius writes signum cum dare coepisset, “when he had begun to give the signal”,[2][5] and Plautus coepī observāre “I began to watch”.[2] De Vaan dates the present coepiō from Plautus.[4]
Semantic evolution
Coepī means “I began”, with an infinitive (flūmen trānsīre coepērunt); with a passive infinitive the passive form is used (pōns īnstituī coeptus est “the building of the bridge was begun”).[2] It is used absolutely, “to begin (to speak)”, with an accusative object, “to begin, set on foot”, and intransitively of events, “to begin” (ubi silentium coepit).[2] The participle coeptus means “begun” and, with an active sense, “having begun”.[2]
The noun coeptum “undertaking” and the frequentative coeptō “to begin” are formed from it.[4][1]
