Book excerpt: The Hittite language is the earliest preserved member of the Indo-European family of languages. It was written on clay tablets in central Asia Minor over a five hundred year span (ca. 1650-1180 B.C.) which witnessed the rise, the floruit, and the decline of many political powers in the Near East. The Hittite Dictionary of the Oriental Institute of the University of Chicago (CHD) is a comprehensive, bilingual Hittite-English dictionary. The CHD is not just a list of words and their meanings, but rather a 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.
