Pronunciation

  • IPA (Ecclesiastical): [akˈtiː.vus][1]

Forms

āctīvus (feminine āctīva, neuter āctīvum, adverb āctīvē); first/second-declension adjective[1]

Etymology

It is from Latin agō (“to do, drive”) + -īvus.[2][1] The grammatical sense is a semantic loan from Ancient Greek ἐνεργητικός (energētikós).[1]

Earliest recorded meaning

Seneca the Younger writes that philosophy is both contemplative and active, and Quintilian uses it of the practical arts.[3][4] Köbler dates Seneca 4 BC–65 AD and Quintilian about 35–95/96 AD.[5]

Semantic evolution

It meant practical or active, in contrast to contemplative or speculative, of philosophy and the arts.[2][3] The grammarians used it of active verbs, which express an action done to something else, opposed to passive.[2][6] Lactantius has an active element opposed to a passive one.[6]

Medieval writers used it of active forces opposed to passive ones in natural philosophy, and of the vita activa, the active life, as opposed to the contemplative.[7][8] English active is recorded from the mid-14th century, first of worldly activity as opposed to the monastic life.[9]
