Bauer's Lexicon

The origin may be traced to Erwin Preuschen's Vollständiges Griechisch-Deutsches Handwörterbuch zu den Schriften des Neuen Testaments und der übrigen urchristlichen Literatur (1910).

[2] Walter Bauer extensively revised this work, as Griechisch-deutsches Wörterbuch zu den Schriften des Neuen Testaments und der übrigen urchristlichen Literatur.

This English edition is often referenced by an abbreviation of the authors - Bauer, Arndt, and Gingrich (BAG).

The second English edition was published in 1979 with the additional help of Frederick William Danker due to the death of Arndt in 1957.

This second edition, Bauer-Danker Greek Lexicon of the New Testament, is commonly known as BAGD (due to the abbreviation of the contributors Bauer–Arndt–Gingrich–Danker).
