Pronunciation

  • Classical: [ɔ.pɛˈraː.tɔr][1]
  • Ecclesiastical: [o.peˈraː.tor][1]

Forms

operātor m (genitive operātōris); third declension[1]

Etymology

It is from Latin operor (“to work”) + -tor, an agent noun.[2][3][4] De Vaan explains operor as a late back-formation from operātus (“busy, absorbed”), an adjective made from opera (“effort, activity”); that is a derivative of opus “work”, which goes back to Proto-Italic *opes- and Proto-Indo-European *h₃ep-os (“work”).[5]

Earliest recorded meaning

Tertullian is the first to use it, in the Apology, for a worker or maker.[6][3][7] The TLL calls it a word of the Christian writers.[2]

Semantic evolution

Firmicus Maternus and Lactantius use it for a worker.[6][3][8] In Christian writers it is one who does good or practises the law, in Ambrose, and the maker of the world, in Jerome's operator mundi.[8] It also appears in the Vulgate,[6] and in the poetry of Paulinus of Nola, Sedulius, Venantius Fortunatus and Arator.[2]

In Medieval Latin it meant a workman[9][10] and, in British sources, a labourer or a customary tenant who owed work, a supporter or intercessor, the doer of a deed, God as creator, and the player of an instrument as distinct from the singer.[11]

English operator (1590s) comes from the verb operate or from this Late Latin word.[12]
