Of the 41,000 words used by Greek authors down to 300 BC about seven-eighths are derivatives or compounds, and their formation is sufficiently explained in Liddell and Scott’s Lexicon. The remaining 5,000 form the subject of the present work, Etyma Graeca: An Etymological Lexicon of Classical Greek. In part one, they are arranged alphabetically, in part two according to the etymological processes involved in them.

Edward Ross Wharton found that the writers of the classical period of Latin literature, down to the death of Trajan in AD 117, used 26,326 words (excluding proper names), all of which except 4,320 sufficiently explain their own formation—thus are derivatives or compounds of these 4,320 words. In Etyma Latina: An Etymological Lexicon of Classical Latin, Wharton treats 3,055 of these 4,320 words, being those found in the 16 Latin authors of the first rank: Plautus, Terence, Cicero, Caesar, Catullus, Lucretius, Sallust, Vergil, Horace, Livy, Tibullus, Propertius, Ovid, Persius, Tactitus, and Juvenal.
