This is the first comprehensive dictionary of the Hebrew and Aramaic component of Modern Ottoman Judezmo – the traditional language of the Turkish and Balkan Sephardim, descendants of the Jews exiled from Spain in 1492. Its over 5000 entries and subentries reveal popular pronunciations of the words as well as the creative grammatical constructions, imaginative semantic innovations, and idiomatic expressions, proverbs and sayings incorporating Hebrew and Aramaic elements, which form a part of the unique Jewish subculture created by the Ottoman Sephardim. The dictionary is preceded by an overview of the Judezmo (also known as Judeo-Spanish, Ladino) language in its historical development, and an analysis of the Hebrew and Aramaic elements used by Judezmo speakers before the modern period covered by the dictionary
