This volume of the Hittite Dictionary of the Oriental Institute of the University of Chicago (CHD) is the complete volume of the letter S (-sa to suu-), including fascicles 1-4. The CHD is a comprehensive, bilingual Hittite-English dictionary. The CHD is not just a list of words and their meanings, but rather an encyclopedic dictionary that reflects and illustrates the ideas and material world of Hittite society through its lexicon. Published letter by letter, the CHD is a long-term project and the result of a painstaking process of cultural, historical, and lexical investigation for all those interested in Hittite culture and history. The CHD is the only such project in the English speaking world.
