Etymology: "Diester" is a plain chemical compound name built from two parts. The first, "di-", comes from Ancient Greek "dis" or "di-", meaning "two" or "twice," and passed into English through Latin. The second, "ester," is a chemistry coinage: in 1852 the German chemist Leopold Gmelin, who was working on the compounds formed when acids combine with alcohols, drew on German "Essig," meaning vinegar, and its older form "Essigäther" to name them. Gmelin's choice of name came from the way acetic acid, the sharp acid of vinegar, was among the earliest substances studied this way. A diester, then, is a molecule containing two ester groups. Chemists used "di-" as a standard prefix for counting such groups, following the same pattern as "diol" for a molecule with two alcohol groups. The term is therefore a systematic label rather than an old name carried over from earlier chemistry.
