Forms

conclusif (feminine conclusive, masculine plural conclusifs, feminine plural conclusives)[1]

Etymology

It is borrowed from Late Latin conclūsīvus (“conclusive”), a Christian Latin word,[2] which the Grand Robert, the GLLF and the Académie call Scholastic Latin.[3][4][5] The Latin adjective is formed on conclūsum, the supine of conclūdō (“to shut up, conclude”), the source of conclure.[2][4][6]

Cognate with Old Occitan conclusiu, Spanish conclusivo and Italian conclusivo.[6] The English word conclusive (1610s) was taken from the French adjective.[7]

Earliest recorded meaning

Its first record is in the chronicle of Georges Chastellain (about 1460), in the phrase tendant a fin conclusive “aiming at a final end”, where it means “that brings to a conclusion”.[2][8][4]

Semantic evolution

In Middle French it was used in phrases such as fin conclusive and termination conclusive, of what ends or concludes a matter or a speech;[8][9] the TLFi follows it to 1510 and then finds it again only in the Académie's dictionary of 1798.[2] That edition defines it as “which concludes, which ends” and calls car a conjonction conclusive;[10] the later editions give donc as the example.[5][2]

Its modern use is learned: in logic and rhetoric it qualifies a proposition or passage that states a conclusion, in grammar a conjunction that introduces one, and in music a chord or note that brings a piece to its close.[2][11] The TLFi labels the word as dated,[2] and the Académie warns against using it for concluant “convincing”.[5]

Timeline

  • c. 1460 – Georges Chastellain uses fin conclusive in his chronicle.[2][8]
  • c. 1500 – Fin conclusive appears in the poems of Antitus.[8]
  • 1510 – Last Middle French record cited by the TLFi, from Huguet.[2][9]
  • 1798 – The Académie records it again, with car as a conjonction conclusive.[2][10]
  • 1610s – English adopts it as conclusive.[7]

Meanings

Adjective

  1. That states or marks a conclusion, of a statement, passage or argument: un chapitre conclusif.[11][12][5]
  2. (grammar) Introducing a conclusion: conjonction conclusive, said of donc.[2][5]
  3. (music) That brings a piece to its close: accord conclusif, note conclusive.[2][11]

Usage notes

The Académie advises against using conclusif where concluant “convincing, decisive” is meant.[5]
