This volume contains a detailed grammatical description of Jibbali (or Shaḥri), an unwritten Semitic language spoken in Oman. This is first grammar of its kind. The large corpus of texts from various sources make this a very valuable resource.

Aaron D. Rubin, Ph.D. (2004) Harvard University, is a Professor at Penn State University. He has published widely on the Semitic languages, including four previous books and numerous articles. His grammar of Mehri appeared in 2010 (Brill).
