"There are basically two types of Arabic: the local vernaculars-which are used in everyday life-and Modern Standard Arabic, which is restricted to writing and to speaking in formal settings. Anyone wanting to have a good command of the Arabic language must learn both varieties. kullu tamam! takes account of this diversity in two ways: it introduces the student to the language by means of Egyptian Colloquial Arabic, and provides a basis for those who want to go on to learn Modern Standard Arabic. This is done by using the grammatical terminology common to both varieties of Arabic, by offering many vocabulary items current in both the vernacular and the standard variety, and-in the later lessons-by introducing the Arabic script."
