The present study attempts to investigate variations in the dialects in Sinai. Egypt is a country where Arabic is spoken; however, there are regional variations. Sinai tribal dialects vary in pronunciation. The primarily purpose of this study is documenting phonological variations in the different reigns of Sinai. There are many other tribes in Sinai; however, this study focusses on three of them: the Sawarka, Tarabin, and Rumailat. Every tribe can be identified from other tribes by their unique dialect. Despite the fact that all Bedouins and Sedentary in any tribe speak Arabic, each tribe has certain variations in word phonetics. There are people who live in towns and others who live in the desert within every tribe. The phonetic distinctions between the Sinai dialects can be clearly seen via the study of phonetics. Because Bedouin pronounce their letters correctly, we can distinguish them from urban people based on phonetic differences in their dialect.
