Forms
testāmentum n (genitive testāmentī); second declension[1]
Etymology
It is formed from Latin testor (“to call to witness, make a will”) + -mentum.[2][1][3] De Vaan derives testor from testis (“witness”), which he traces to Proto-Italic *tri-sto- and Proto-Indo-European *trito-sth₂-o- (“standing by as a third”).[4] The Christian sense comes from its use to render Ancient Greek διαθήκη (diathḗkē, “covenant; will”).[1][5]
Earliest recorded meaning
De Vaan dates it from Plautus,[4] and the OLD's first example is in Plautus' Asinaria.[2] Köbler first records it in Cicero.[6]
Semantic evolution
Testāmentum is a will, the last declaration of what one wants done after one's death, as Gellius defines it.[2][3] Apuleius makes a joke of it, as if from testis “testicle”.[2]
In Christian Latin it renders the Greek word for “covenant”, and so names the covenant of God, and the Old and New Testaments, Vetus and Novum Testāmentum, and the Bible.[5][1] In medieval Latin it was also a deed of gift to take effect at death, any written deed, and a royal diploma.[7]
