"This meticulously researched volume fills a substantial gap in the dialect map of Egypt. […] … this volume is an excellent contribution to the field of Arabic dialectology, and will be of particular interest to Arabists, Semiticists, dialectologists, and sociolinguists." - Domenyk Eades, in: Journal of the American Oriental Society 133.4 (2013)"Under any circumstances, de Jong’s book would be a major contribution to Arabic dialectology. Its value is enhanced by the present unhappy situation in the Sinai, where substantial further research is unlikely to be carried out in the foreseeable future. In all probability we shall never learn more about many of the Sinai dialects than what de Jong reports. The material that he gives us is, however, so rich that even without additional information from the peninsula, it will nourish much future scholarship." - Frank H. Stewart, in: JSAI (2017)
