Forms

spōnsiō f (genitive spōnsiōnis); third declension[1]

Etymology

It is from Latin spondeō (“to pledge”) + -tiō.[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

The OLD's earliest citations are Plautus, of a legal wager and of money given as security, and Köbler lists the Twelve Tables.[2][4] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

A legal and diplomatic term, it meant a solemn promise, guarantee, pledge, as in Cicero; in law a kind of wager in which a litigant undertook to pay a sum if his claim failed, as in Plautus and Cicero; and money given as security.[2][5][6]

In Ecclesiastical Latin it means promise, guarantee, security, agreement, bet.[7] Medieval Latin used it for a surety, pledge, and British Medieval Latin also for a promise of marriage.[8][9]

Timeline

  • c. 250–184 BC – Plautus uses it of a wager and of security.[2][4]
  • 81–43 BC – Cicero uses it of a solemn promise.[2][4]
