From earlier Old Latin coëpiō, coapiō, with a trisyllabic stem, from co- + apiō (literally “to lay hold of something on different sides, to lay hold of”). Late Latin coepiō, with a disyllabic stem, is a back-formation.
coepī (perfect infinitive coepisse, supine coeptum); third conjugation, no present stem
