compound formed by an acid joined to an alcohol, 1852, coined in German in 1848 by German chemist Leopold Gmelin (1788-1853), professor at Heidelberg. The name is "apparently a pure invention" [Flood], perhaps a contraction of or abstraction from Essig?ther, the German name for ethyl acetate, from Essig "vinegar" + ?ther "ether" (see ether). Essig is from Old High German ezzih, from a metathesis of Latin acetum (see vinegar).
