es·ter

 (ĕs′tər)
n.
Any of a class of compounds derived from an oxyacid, usually resulting from the reaction of an oxyacid and an alcohol with the elimination of water.

[German, short for Essigäther : Essig, vinegar (from Middle High German ezzich, from Old High German ezzīh, from Latin acētum; see ak- in Indo-European roots) + Äther, ether (from Latin aethēr; see ether).]

ester

(ˈɛstə)
n
(Chemistry) chem any of a class of compounds produced by reaction between acids and alcohols with the elimination of water. Esters with low molecular weights, such as ethyl acetate, are usually volatile fragrant liquids; fats are solid esters
[C19: from German, probably a contraction of Essigäther acetic ether, from Essig vinegar (ultimately from Latin acētum) + Äther ether]

es•ter

(ˈɛs tər)

n.
a chemical compound produced by the reaction between an acid and an alcohol with the elimination of a molecule of water, as ethyl acetate, C4H8O2, or methyl methacrylate, C5H8O2.
[1850–55; < German (1848), probably b. Essig vinegar and Ӓther ether]

es·ter

(ĕs′tər)
An organic compound formed when an acid and an alcohol combine and release water. Animal and vegetable fats and oils are esters.
