Pronunciation

  • IPA (Classical): [ˈaːk.tɔr][1]
  • IPA (Ecclesiastical): [ˈak.tor][1]

Forms

āctor m (genitive āctōris, feminine āctrīx); third declension[1]

Etymology

It is an agent noun, from Latin āctus + -tor, the participle of agō “to drive, do”.[1][2]

Earliest recorded meaning

Plautus uses it of a doer: in the Bacchides a slave says it is not the deed but the doer that wounds his heart.[2] Köbler dates Plautus c. 250–184 BC.[3]

Semantic evolution

Its literal sense was one who drives, a herdsman or drover, as in Ovid's pecoris āctor.[2][4] In general use it was a doer or agent, and Cicero calls Cato the leader, adviser and doer of the events.[4][2] In law it was the pleader of a case, especially the prosecutor or plaintiff.[2] On the stage it was a player, already in Terence and Cicero.[2] Columella and Pliny the Younger use it of a steward or bailiff of an estate, and Tacitus of imperial agents.[2] Döderlein notes that āctor is the respectable term for a player, while lūdiō is the professional comedian.[5]

In medieval Latin it was an attorney, trustee or agent, notably the steward of a church's property.[6] British writers used it of an agent and of the author of a book, by confusion with auctor.[7] English actor is recorded in the late 14th century as an overseer or steward.[8]
