In Coastal Dhofari Arabic: A Sketch Grammar , Richard Davey provides a detailed description of a hitherto neglected Arabic dialect found in southern Oman. Previously recorded by Rhodokanakis, as part of the südarabische Expedition of the Austrian Imperial Academy, the dialect presented here offers a specific account of the day-to-day language spoken by the historical sedentary, coastal community. Using data collected during 2010-2012, Richard Davey delivers an overview of the phonology, morphology and syntax of this variety. In addition to this, a lexicon of coastal Dhofari Arabic is provided, along with a discussion of its grammaticalized features. It is a timely account of a dialect that is endangered due to development, modernization, and the resulting social changes in Dhofar.
