Pronunciation

Forms

hydrate m (plural hydrates)[1] First spelled hidrate (1802).[2][3]

Etymology

It is a learned formation from French hydr- + -ate,[3][4][1] on Ancient Greek ὕδωρ (húdōr, “water”).[2][5][6] Etymonline credits the word to the chemist Joseph-Louis Proust, about 1800.[7]

Earliest recorded meaning

It is first recorded in 1802, spelled hidrate, in the Annales du Muséum national d'histoire naturelle, for what was later called a hydroxide.[2][4][8]

Semantic evolution

The name hydroxyde replaced it in that sense from 1842.[8] From 1845 it was used for a compound of a simple or compound body with one or more molecules of water,[2][8] and in 1872 it entered the phrase hydrate de carbone for organic compounds of carbon, hydrogen and oxygen, now called glucides.[2][8][9] The verb hydrater, first as the participle hydraté (1805), was formed from it.[8] English hydrate was taken from French in 1802.[7]
