Forms

poison m or (Louisiana) f (plural poisons)[1] Old French poisun, puisun, puison, feminine until the 16th century.[2][3][4]

Etymology

It is inherited from Old French poison, inherited from Latin pōtiō (“a drinking, a drink, a medicinal draught, a poisoned draught, a love potion”).[2][5][4] The Latin noun was formed on the supine of pōtō (“to drink”), a frequent verb that did not survive in the Romance languages, where bibō took its place.[4] The narrowing from “drink” to “poisoned drink” had already begun in Late Latin, a development Bloch and Wartburg and Rey compare with that of the Greek word behind pharmacie.[5][4]

The word was feminine like its Latin source until the 16th century or the beginning of the 17th, and it is still feminine in most dialects;[2][5][4] the masculine probably came from venin, from Latin venēnum.[2][4] The learned potion is a doublet taken straight from the Latin word.[1][4] Cognate with Occitan poizo, and with the borrowings English poison and English potion.[6][1]

Earliest recorded meaning

Its first record is in the Judeo-French glosses of Rashi, at the end of the 11th century, with the general sense “a drink”.[2][4] From 1155, in Wace's Brut, it is usually a suspicious or poisoned draught.[2]

Semantic evolution

In Old French the word kept the whole Latin range: a drink, a poisoned draught (1155), a healing potion or remedy (about 1165) and a magic philtre (about 1165).[2][4] Rey explains the loss of the favourable senses by the awkwardness of a word meaning both a cure and a killing drink; the sense “remedy” passed to the learned doublet potion.[4]

The modern sense “deadly substance”, whatever its form, is found from 1342, and the figurative “something pernicious” from 1544 (Calvin).[2][4] Middle French also used it for poisoning (1558) and, in 16th-century love poetry, for a beloved woman (1554); later it meant a stench (before 1646) and a very bad dish (1665), senses that have gone.[2][4] Exaggerating, it came to name any harmful food or drink (about 1695).[4]

Popular speech made it an insult for a woman (1789, Restif de la Bretonne), then for a disagreeable person and an insufferable child, and a word for a tiresome chore.[2][4][7][8] Its derivative empoisonner is recorded about 1130.[4]
