Forms

testātus (feminine testāta, neuter testātum, comparative testātior); first/second-declension adjective[1]

Etymology

Used as an adjective, it is the participle from Latin testor (“to call to witness, bear witness”).[1][2] De Vaan thinks the verb was derived directly from testis (“witness”), which he reconstructs as Proto-Italic *tri-sto/i-, with the generally accepted original meaning “third standing by”, from Proto-Indo-European *trito-sth2-o-.[3] He compares Oscan trstus (“witnesses”) and Old Irish triss (“third”).[3]

Earliest recorded meaning

Köbler records it first in Cicero,[4] who in the Verrines wants a matter to be as clear and as well attested as possible (quam maxime clara et testata).[1]

Semantic evolution

Its classical sense is known on good evidence, well attested: Cicero uses it several times, Hirtius of making the punishment of wrongdoers better known, and Nepos, Ovid and Valerius Maximus also have it.[1][5] Augustine uses the superlative testatissimus of wonders that were fully attested.[5] In the jurists, as the counterpart of intestātus, it describes a person who has left a valid will, as in Ulpian.[1] Niermeyer gives a medieval sense relating to a gift made on account of death.[6]
