Pronunciation

  • IPA (Classical): [proːˈmɪs.sũː][1]
  • IPA (Ecclesiastical): [proˈmis.sum][1]

Forms

prōmissum n (genitive prōmissī); second declension[1]

Etymology

It is the neuter of prōmissus, the participle of prōmittō “to send forth, promise”, used as a noun.[2][1]

Earliest recorded meaning

Plautus, in the Amphitruo, has someone begged to keep a promise, and in the Pseudolus “be sure to remember your promise”.[2] Köbler dates Plautus c. 250–184 BC.[3]

Semantic evolution

It was a promise or assurance, and sometimes the thing promised, as Terence's time to fulfil promises.[2] Cicero uses prōmissum facere and prōmissa servāre of keeping promises, Virgil prōmissīs manēre, and Catullus prōmissa dare.[4][5] It was also a prediction given as certain, as Cicero's promises of the Chaldeans, and an assertion given as true, as Pliny's absurd claim of Democritus.[2]

In medieval Latin it appears in charters.[3] English promise is recorded around 1400, through Old French promesse.[6]
