Origin and history of ester

ester(n.)

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 Essigäther, the German name for ethyl acetate, from Essig "vinegar" + Äther "ether" (see ether). Essig is from Old High German ezzih, from a metathesis of Latin acetum (see vinegar).

also from 1852

ether(n.)

late 14c., "upper regions of space," from Old French ether (12c.) and directly from Latin aether "the upper pure, bright air; sky, firmament," from Greek aithēr "upper air; bright, purer air; the sky" (opposed to aēr "the lower air"), from aithein "to burn, shine," from PIE *aidh- "to burn" (see edifice).

In ancient cosmology, the element that filled all space beyond the sphere of the moon, constituting the substance of the stars and planets. Conceived of as a purer form of fire or air, or as a fifth element. From 17c.-19c., it was the scientific word for an assumed "frame of reference" for forces in the universe, perhaps without material properties. The concept was shaken by the Michelson-Morley experiment (1887) and discarded early 20c. after the Theory of Relativity won acceptance, but before it went it gave rise to the colloquial use of ether for "the radio" (1899).

The name also was bestowed c. 1730 (Frobenius; in English by 1757) on a volatile chemical compound known since 14c. for its lightness and lack of color (its anesthetic properties weren't fully established until 1842).

vinegar(n.)

diluted impure acetic acid, early 14c., vinegre, usually "wine vinegar," from Anglo-French vinegre, Old French vinaigre "vinegar," from vin "wine" (from Latin vinum; see wine (n.)) + aigre "sour" (see eager). In Latin, it was vinum acetum "wine turned sour," acetum for short (see acetic), also used figuratively for "wit, shrewdness;" and compare Greek oxos "wine vinegar," which is related to oxys "sharp" (from PIE root *ak- "be sharp, rise (out) to a point, pierce"). Related: Vinegary; vinegarish.
