Pronunciation

  • IPA (Classical): [ˈspõː.sɔr][1]
  • IPA (Ecclesiastical): [ˈspɔn.sor][1]

Forms

spōnsor m (genitive spōnsōris); third declension[1]

Etymology

It is from Latin spondeō (“to pledge”) + -tor.[2][1] De Vaan traces ⟨spondeō⟩ to Proto-Italic *spondeje/o- (“to libate many times; pledge”), Proto-Indo-European *spond-éye/o- (“to libate”), cognate with Ancient Greek σπένδω (spéndō, “to pour a libation”) and Hittite išpant- (“to libate”).[3]

Earliest recorded meaning

Köbler's earliest source is Cicero, and Gaffiot cites his letters.[4][5] Köbler dates Cicero 81–43 BC.[4]

Semantic evolution

In law it meant one who formally guarantees the good faith of another, a surety, bondsman, as in Cicero, who also has prōmissōrum alicuius spōnsor “guarantor of someone's promises”.[2][6][5]

In Ecclesiastical and Medieval Latin it was a sponsor at baptism, a godparent.[7][8][9] English sponsor (1650s, first “godparent”) is from it, and German Sponsor too.[10][4]

Timeline

  • 81–43 BC – Cicero uses it.[5][4]
  • 1650s – English sponsor is recorded.[10]
