Forms

testāmentārius (feminine testāmentāria, neuter testāmentārium); first/second-declension adjective; as a noun, testāmentārius m (genitive testāmentāriī); second declension[1][2]

Etymology

It is from Latin testāmentum (“will”) + -ārius.[1][2] Köbler traces it further to testis (“witness”).[3]

Earliest recorded meaning

It is first found in Cicero,[3] who names the Cornelian law on wills (lēx Cornēlia testāmentāria) in the Verrines,[2][4][5] and uses the noun of a forger of wills in his list of a poisoner, a will-forger and an assassin (cum venēficō, cum testāmentāriō, cum sīcāriō).[1][2]

Semantic evolution

Pliny the Elder speaks of adoption by will,[2][4] and the jurists of inheritances under a will.[2][4] In the Digest and in inscriptions the noun is the man employed to draw up wills,[1][4] sometimes with a suggestion of forgery and similar malpractice.[1]

In medieval Latin the noun also meant the executor of a will,[6][7] the adjective could mean serving as documentary evidence,[6] and a neuter testāmentārium was a treatise on wills.[7] It survives in Italian testamentario.[5]
