A Greek–English Lexicon

A Greek–English Lexicon, often referred to as Liddell & Scott () or Liddell–Scott–Jones (LSJ), is a standard lexicographical work of the Ancient Greek language originally edited by Henry George Liddell, Robert Scott, Henry Stuart Jones, and Roderick McKenzie and published in 1843 by the Oxford University Press.

It was most recently revised for its ninth edition of 1940. Abridged versions and a supplement exist. It was initially the basis for the 2021 Cambridge Greek Lexicon, although subsequently that became a complete rewrite from scratch.

Liddell and Scott's lexicon (1843–1940)

The lexicon was begun in the 19th century, and is now in its ninth (revised) edition, published in 1940. It was based on the earlier Handwörterbuch der griechischen Sprache by the German lexicographer Franz Passow (first published in 1819, fourth edition 1831), which in turn was based on Johann Gottlob Schneider's Kritisches griechisch-deutsches Handwörterbuch. The Lexicon has served as the basis for all later lexicographical work on the ancient Greek language, such as the ongoing Greek–Spanish dictionary project Diccionario Griego–Español (DGE).

It is now conventionally referred to as Liddell & Scott, Liddell–Scott–Jones, or LSJ, and its three sizes are sometimes referred to as "The Little Liddell", "The Middle Liddell" and "The Big Liddell" or "The Great Scott". The LSJ main edition has 116,502 entries.

According to Stuart Jones's preface to the ninth (1925) edition, the creation of the Lexicon was originally proposed by David Alphonso Talboys, an Oxford publisher.
