Forms

testimōnium n (genitive testimōniī or testimōnī); second declension[1]

Etymology

It is from testis “witness” with the suffix -mōnium.[2][1][3] An inscription has ⟨testu-⟩.[2]

Earliest recorded meaning

The OLD's earliest citation is from the Twelve Tables, of a witness's testimony.[2] Köbler dates them about 450 BC.[4]

Semantic evolution

It meant evidence given by a witness, testimony, as Plautus' false suits pressed with false testimony and Cicero's testimōnium dīcere.[2][5][6] In Gaius it meant the attestation of a witness at a legal act, and in Cicero any corroboration, especially a writer's words, and testimony to someone's merits.[2] From the Rhetorica ad Herennium it meant a proof, token.[2]

In Ecclesiastical Latin it meant testimony, evidence, and in canon law a deposition under oath before a judge.[7] Medieval Latin used it for a witness's signature, a witness, an oath-helper and reputation.[8] It survives in Italian testimonio and Spanish testimonio, and Old North French testimonie gave English testimony about 1400.[1][3]
