This study offers a thorough analysis of the bedouin dialects of the northern Sinai littoral. Proposing 82 criteria and introducing 'partial isoglosses' to typologically measure dialects, the author shows that three of five dialect groups identified form a linguistic continuum.
'...de Jong has made a pioneering work and showed once again how interesting and important the study of spoken Arabic is…de Jong’s book should not be missed on the bookshelf of any student of Arabic dialectology and he is only to be congratulated on a splendid job.’ Jan Retsö, Acta Orienatalia , 2001. ‘The result of painstaking research work is praiseworthy indeed: not only is the documentation convincing, but the study also provides effective tools for future investigations.’ Heikka Palva, Studia Orientalia.
Rudolf E. de Jong, Ph.D. (1999) in Humanities, University of Amsterdam, currently works as an independent researcher of Arabic dialects. He has published two articles on the dialect of the Fayyoum and several on the dialects of Sinai in various journals.
