āctuōsus (feminine āctuōsa, neuter āctuōsum, adverb āctuōsē); first/second-declension adjective[1]
Etymology
It is from Latin āctus (“impulse, motion, act”) + -ōsus, like ⟨flexuōsus⟩ and ⟨quaestuōsus⟩.[2][1] ⟨āctus⟩ is from agō (“to do, drive”).[1][3] De Vaan traces ⟨agō⟩ to Proto-Italic *ag-e/o- (“to do, act”), from Proto-Indo-European *h₂eǵ-e/o- (“to drive, lead”).[4]
Earliest recorded meaning
Its earliest source is Cicero, āctuōsa virtūs “active virtue”.[3][5] Köbler dates Cicero 81–43 BC.[3]
Semantic evolution
It meant marked by or full of activity, energetic, busy, as in Cicero, and Lewis & Short note the added idea of zeal and inner impulse, distinguishing it from industrius.[2][6][5]
British Medieval Latin used it for practical, of the active way of life.[7]
