The Aramaic language has continued to be spoken in various dialects down to modern times. Many of these dialects, however, are now endangered due to political events in the Middle East over the last hundred years. This work, in three volumes, presents a description of one such endangered neo-Aramaic dialect, that of the Assyrian Christian community of the Barwar region in northern Iraq. It is a unique record of the dialect based on interviews with the surviving older generation of the community. The work consists of three volumes. Volume one contains a detailed grammatical description of the dialect, including sections on phonology, morphology and syntax. Volume two contains an extensive glossary of the lexicon of the dialect with illustrations of various aspects of the material culture. Volume three contains transcriptions of numerous recorded texts, including folktales, ethnographic texts, songs, and proverbs.
