Pronunciation

  • IPA (Classical): [kõːˈspɔn.de.oː][1]
  • IPA (Ecclesiastical): [konˈspɔn.de.o][1]

Forms

cōnspondeō (present infinitive cōnspondēre, perfect active cōnspondī, supine cōnspōnsum); second conjugation, no passive[1] An old spelling consposos is recorded by Paul the Deacon's epitome of Festus.[2][3]

Etymology

It is from Latin con- (“together”) + spondeō (“to pledge”).[2][4][1] De Vaan traces ⟨spondeō⟩ to Proto-Italic *spondeje/o- (“to pour libations many times, pledge”), from Proto-Indo-European *spond-eye/o- (“to pour a libation”).[5]

Earliest recorded meaning

The TLL cites Naevius' comedies and the decree on the Bacchanalia, which forbids men to have conspired or exchanged pledges among themselves (neve conspondise).[4] Köbler dates Naevius c. 235–200 BC.[6]

Semantic evolution

It meant to exchange pledges, engage mutually, and in the participle cōnspōnsus bound by mutual pledges; the glossaries equate it with conprōmissum and the TLL with coniūrāre “to conspire”.[2][4] Ausonius has cōnspōnsum foedus “a treaty mutually agreed”.[7]
