Pronunciation

  • Classical: [ˈspõː.sʊs][1]
  • Ecclesiastical: [ˈspɔn.sus][1]

Forms

spōnsus m (genitive spōnsī, feminine spōnsa); second declension[1]

Etymology

The bridegroom is from Latin spondeō (“to pledge, promise solemnly”): its perfect passive participle, “betrothed”, used as a noun.[1][2][3] De Vaan reconstructs that verb as Proto-Italic *spondeje/o- (“to libate many times”), whence “to pledge”, and Proto-Indo-European *spond-eie/o- (“to libate”).[4] Cognate with Hittite išpant- (“to libate”) and Ancient Greek σπένδω (spéndō, “to pour a libation”).[4]

Earliest recorded meaning

De Vaan dates it from Titinius,[4][5] who writes of a girl proud of her betrothed, virgō spōnsō superba, and has accēde ad spōnsum audācter, “go boldly up to the bridegroom”.[6][7]

Semantic evolution

Cicero uses it in the De inventione, and Horace has spōnsus rēgius, a royal bridegroom;[6][7] Horace and Catullus also use it of suitors, Horace of Penelope's.[7][8] An inscription seems to use it of a husband.[2] In Ecclesiastical Latin it is a bridegroom or spouse, and the plural an engaged couple;[9] in medieval Latin it can mean a husband,[10] and British writers use it of a fiancé and of a bridegroom or newly married man.[11] Through Old French it gave English spouse.[3]

Pronunciation

  • Classical: [ˈspõː.sʊs][1]
  • Ecclesiastical: [ˈspɔn.sus][1]

Forms

spōnsus m (genitive spōnsūs); fourth declension[1]

Etymology

The noun meaning a pledge is from Latin spondeō (“to pledge, promise solemnly”) + -tus, an action noun of the fourth declension.[2][1]

Earliest recorded meaning

Varro, in the De lingua Latina, writes of a man bound by a pledge, quod spōnsū erat alligātus, and of suing on a pledge, agere ex spōnsū.[6][12]

Semantic evolution

The OLD explains the name from the formula of the pledge, the question spondēsne? answered by spondeō.[2] Cicero uses it of a suretyship in a letter to Atticus,[12][8] Servius Sulpicius, quoted by Gellius, has ex spōnsū agere, and Phaedrus spōnsū locāre.[6][12] Gaius names a lēx Fūria dē spōnsū, and the jurist Paul an interrogātiō spōnsūs.[12][6] Lewis & Short call it rare but classical.[6] In Ecclesiastical Latin it is a covenant or engagement, bail or surety.[9]

Timeline

  • 116–27 BC – Varro uses it of a legal pledge.[6][5]
  • 81–43 BC – Cicero uses it of a suretyship.[12][5]
  • 140–180 AD – Gaius names the lēx Fūria dē spōnsū.[12][5]

Meanings

  2. Suretyship, bail.[2][6][12]
