Etymologicum Magnum

The oldest Greek lexicon in existence, dating probably from the tenth century A.D., and by an unknown author. It professes to give the roots of the words contained in it. The proposed etymologies are often mere guesses, but the work is historically valuable as embodying a great number of traditions and notices of the meanings of unusual words. There are modern editions by Schäfer (Leipzig, 1816), Sturz (Etymologicum Gudianum) (Leipzig, 1818), and Gaisford (Oxford, 1849). See Lexicon.
