Pronunciation

  • Classical: [kɔnˈdʊk.tɔr][1]
  • Ecclesiastical: [konˈduk.tor][1]

Forms

conductor m (genitive conductōris, feminine conductrīx); third declension[1]

Etymology

It is from Latin condūcō (“to bring together; to hire”) + -tor, the agent noun of the verb.[2][1] That verb is formed from con- and dūcō (“to lead”),[1][3] which goes back to Proto-Italic *doukō and Proto-Indo-European *dewk- (“to draw, lead”).[1][3]

Earliest recorded meaning

It is first found in Plautus,[3] in the prologue of the Asinaria, which wishes good fortune to the troupe, its owners and its conductores, the people who hire it.[2][4]

Semantic evolution

In Classical Latin it named either side of a hiring or contract other than the owner: the person who hires others for wages, the contractor who undertakes a piece of work, and the lessee or tenant of a house or farm.[2][4] L&S calls it rare and mostly used without a complement.[4] It was also used of the contractors who farmed public revenues;[5] Isidore of Seville explains the publicani as such contractors.[5]

Etymonline gives a Late Latin sense “carrier”.[6] Medieval Latin used it for a manager of a manor, an escort, a waggoner and the commander of an army,[7] and English took the word from French in the 1520s in the sense “one who leads or guides”.[6] In New Latin it also names a conductor of heat or electricity.[1]

Timeline

  • c. 250–184 BC – Plautus uses it of those who hire a troupe of actors.[2][4][3]
  • 234–149 BC – Cato uses it of a contractor who undertakes building work on a farm.[2][4][8]
  • 81–43 BC – Cicero uses it of the contractor for a public work.[2][8]
  • c. 50 BC – Caesar uses it of tenants whose yearly rents were remitted.[2][8]
  • c. 560–636 AD – Isidore of Seville explains the publicani as contractors for the public revenues.[5][8]
  • 1520s – English borrows conductor through French, in the sense “one who leads or guides”.[6]
