Crum`s work is the result of more than thirty years of research and collaboration with numerous scholars. Originally published in 1939, it immediately became, and has remained, the definitive dictionary of the Coptic language. Each word is given with variant word-forms, its context in English summary, the original or equivalent words in Greek, and illustration of its use. Indexes of English, Greek, and Arabic words are also provided. The new Foreword by James M. Robinson provides the reader with an up-to-date summary of the current state of Coptic studies.
