Forms

conclure[1]

Etymology

It is borrowed from Latin conclūdō (“to shut up, enclose; to end; to infer”), formed from cum (“with”) and claudō (“to close”), the source of clore.[2][3][4][5] In Church Latin it was used for making peace.[2] Wiktionary treats the Old French verb as already borrowed.[1] Cognate with Old Occitan concluire, Spanish concluir and Italian conchiudere.[6]

Earliest recorded meaning

In the Oxford Psalter (early 12th century) it means to shut in, enclose.[7][2]

Semantic evolution

The sense “to enclose”, still used figuratively in the 16th century for shutting someone in an argument, went out of use before the 17th century.[2][7] It was replaced by the abstract sense of establishing what follows from earlier arguments (Brunetto Latini, about 1260), which also prevailed over “to decide” (15th century, Commynes).[2][7] In Old French and Anglo-Norman it also meant to defeat someone in argument, to convict.[8][3]

The verb took up the Latin sense of negotiating to an end: alliance conclute (1513), a peace, then a bargain.[2][7] Used absolutely, concluez ! was said to a long-winded lawyer (Furetière, 1690).[7] In informal use conclure also means to have sex with someone.[1] Derivatives are concluant and conclusion.[1][3]
