Pronunciation

  • Classical: [adˈjuː.roː][1]
  • Ecclesiastical: [adˈjuː.ro][1]

Forms

adiūrō (present infinitive adiūrāre, perfect active adiūrāvī, supine adiūrātum); first conjugation[1]

Etymology

It is from Latin ad- + iūrō (“to swear”).[2][3] De Vaan lists it among the derivatives of iūs2 (“law, oath”), from which iūrō was formed as a denominative verb, Proto-Italic *jowes-ā-je-;[4] Old Latin has the third person ⟨iouvesat⟩ “swears” in the Duenos inscription.[4] He traces iūs2 to an s-stem going back to Proto-Indo-European *h₂oi-u (“vital force, eternity”).[4] Ancient commentators on Virgil explained the prefix as a mere addition to iūrō or as meaning “very”;[3] Servius also reports that some reserved the compound for swearing that something was not so.[3]

Earliest recorded meaning

De Vaan records it from Plautus on.[4] In the Amphitruo a character demands that the other “swear besides” that he did not mean what he said (adiuret insuper nolle esse dicta).[2][3]

Semantic evolution

In Classical Latin it means to affirm something on oath, with an accusative and infinitive, with ut or absolutely, in Plautus, Terence, Cicero, Livy, Suetonius and Statius.[2][3] Livy also uses it of swearing something in addition to the common oath of all citizens.[5] With a direct object it means to swear by a person or thing: Catullus swears by a head, and Virgil by the head of the Stygian spring.[2][3]

In later Latin it came to mean to put someone under oath, and to entreat someone earnestly, as in Lactantius, Vopiscus and the Vulgate.[3][5] Christian writers such as Minucius Felix and Lactantius use it of adjuring demons by the name of God, that is, of exorcising them.[5][3] In Ecclesiastical Latin it means to adjure or swear.[6] From it English took adjure in the late 14th century.[7]
