Forms

testimōniālis (neuter testimōniāle); third-declension two-termination adjective[1][2]

Etymology

It is from Latin testimōnium + -ālis, an adjective on the noun for testimony.[1][2][3]

Earliest recorded meaning

Tertullian is the first to use it, of a comparison that serves as evidence (comparatio testimonialis).[1][2][4][5]

Semantic evolution

Late Latin used the feminine plural testimoniales (with litterae understood) for written certificates: Vegetius and the Theodosian Code have it.[1][2][4] In medieval Latin the adjective meant “bearing witness”, and as a masculine noun it named a witness;[6] British documents use the neuter as a noun for a written attestation, a testimonial.[7] Humanists kept it: Filelfo heads a letter testimonialis familiaris epistola.[8]

Timeline

  • c. 160–220 AD – Tertullian speaks of a comparison serving as evidence.[1][2][5]
  • c. 400 AD – Vegetius uses testimoniales for certificates.[1][4][5]
  • 438 AD – The Theodosian Code has testimoniales in the same sense.[1][3][5]
