Forms

toxicité f (plural toxicités)[1]

Etymology

It is formed from French toxique + -ité.[2][1][3] The adjective is from Latin toxicum, from Ancient Greek τοξικόν (toxikón), properly the poison smeared on arrows, from τόξον (tóxon, “bow”).[4]

Earliest recorded meaning

It is first recorded in 1865, in the medical dictionary of Littré and Robin, for the property of a substance that can poison a living organism.[2][5][6]

Semantic evolution

Littré's own dictionary gave it in 1872 as a medical term, with the example of thebaine;[7][3] the Grand Robert finds it in 1869.[8] From 1904 it also meant the coefficient of toxicity, the smallest dose that kills, expressed in weight of substance per kilogram of the animal.[3][2] The word gave the antonym atoxicité in the 20th century and écotoxicité in 1989.[6]
