In this major reference tool, Jessie Payne Smith has abridged the great two-volume work, 'Thesaurus Syriacus,' by her late father. But her task was not to simply edit down the earlier, massive tomes. She also provided English translations for each entry and additional notations. Her father's dictionary had translated each Syriac word into Latin. The Latin translations made it more internationally accessible; but with the decline of the use of Latin, it decreased in usefulness. Her labors have insured that it continues to benefit scholars and students of Syriac.
