Forms

complēmentum n (genitive complēmentī); second declension[1]

Etymology

It is from Latin compleō (“to fill up”) + -mentum.[2][3][1]

Earliest recorded meaning

Cicero (81–43 BC), in the Orator, speaks of empty words stuffed into a sentence as fillers of the rhythm, quasi complēmenta numerōrum.[3][4][5]

Semantic evolution

Tacitus writes that the charge of treason was then the finishing touch of every accusation, and a law of 374 in the Theodosian Code uses it of the completion of an accusation.[3][4] Later writers use it for whatever completes something: Firmicus Maternus of the moon's fullness, Vegetius of the completion of a work, Augustine of Pentecost as the mystical completion of Easter;[3] Apringius, commenting on the Apocalypse, of the end of the Greek alphabet.[3] It also came to mean the act of completing or accomplishing, as in Isidore.[3]

In Medieval Latin it also meant the settlement of a debt and the carrying out of a punishment,[6] and scholastic writers in Britain used it for completeness, the full realisation of a being.[7] English complement (late 14th century) comes from it through Old French, and so, by another route, does compliment.[8]

Timeline

  • 81–43 BC – Cicero: words that only fill out the rhythm.[3][5]

  • 343/350 AD – Firmicus Maternus, of the waxing moon.[3][5]
  • 354–430 AD – Augustine: Pentecost completes Easter.[3][5]
  • c. 560–636 AD – Isidore uses it for the fulfilling of commandments.[3][5]
  • late 14th century – English borrows complement through Old French.[8]

Döderlein distinguishes it from supplēmentum: a complēmentum completes and crowns the whole, like a keystone, while a supplementum fills gaps and supplies what is missing.[9]
