Pronunciation

  • IPA: /ˈæk.tɪv/[1]

Etymology

It is inherited from Middle English actif, active,[2] borrowed from Old French actif (feminine active),[2][3] or directly borrowed from Latin āctīvus,[2][3] from āctus “a doing”, the past participle of agō (“I drive, cause to move, do”),[4][5] the source of act.[3] Etymonline takes it to Proto-Indo-European *ag- (“to drive, draw out, move”).[2]

Earliest recorded meaning

“Given to worldly activity”, as opposed to contemplative or monastic: 1340, in the Ayenbite of Inwyt,[3][6] the mid-14th century.[2]

Semantic evolution

As “capable of acting, communicating action”, opposed to passive, it is from the late 14th century,[2][6] about 1400 in the OED.[6] In grammar, of a verb whose subject performs the action, it is from the mid-15th century,[2] and the active voice is recorded from 1765.[2] “Energetic, lively” is from the 1590s,[2] and “working, effective, in operation”, opposed to inactive or extinct, from the 1640s.[2][6] In physics it was used for radioactive from 1900.[6] Activity is from probably before 1400,[3] and activate from 1626, in Bacon.[3]
