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]
