Pronunciation

  • Classical: [kɔnˈjuː.roː][1]
  • Ecclesiastical: [konˈjuː.ro][1]

Forms

coniūrō (present infinitive coniūrāre, perfect active coniūrāvī, supine coniūrātum); first conjugation[1] The Senatus consultum de Bacchanalibus has the archaic perfect infinitive coniourase.[2][3]

Etymology

It is from Latin con- (“with, together”) + iūrō (“to swear”).[2][3][1] De Vaan derives iūrō from iūs (“law, oath”) through a denominative verb Proto-Italic *jowes-ā-je-, and iūs from an s-stem Proto-Italic *jowos, which he takes back to a Proto-Indo-European word for vital force.[4]

Earliest recorded meaning

The earliest example in the OLD is the decree of the Senate on the Bacchanalia, which forbids anyone to swear together with others.[2][3]

Semantic evolution

It is first to take an oath together, as when Caesar has the young men of Italy sworn in for service, and of states to form a league by oath: Virgil has all Latium binding itself in alarm.[2][5] More often it is to join in a plot or conspiracy, as in Cicero's “I would rather have conspired than resisted the conspiracy”.[2] A scholiast on Horace says that conspiring is sometimes said of good men, but coniurāre only of bad.[3] The perfect participle has active sense, and coniūrātī are the sworn conspirators.[5][1] The poem Aetna uses it of winds acting in unison.[2]

Timeline

  • c. 50 BC – Caesar of young men sworn in for service.[2][6]
  • 81–43 BC – Cicero of joining a conspiracy.[2][6]
  • 70–19 BC – Virgil of Latium binding itself together.[2][5][6]
  • late 13th century – English conjure, first “command on oath”, is borrowed through Old French and directly.[7]
