A language is a window to the worlds of its language community, and its morphology is basically the essential frame that marks up its contours. The varieties of a language are the best manifestations of its growth and evolution, reflecting linguistic and cultural deviations characteristic of its speakers. Ibb variety is a dialect of Arabic spoken in Ibb region in Yemen. Its features encode not only the diglossic nature of Arabic speakers throughout the Arab world, but also provide interesting insights into a path of evolution of Arabic language on basis of its morphology. Using nonconcatenative templatic morphology, this book presents detailed morphological examination of this variety in terms of the major parts of speech: verbs, nouns, pronouns, and adjectives. It is hoped that this study, along with parallel studies of other varieties of Arabic, can provide much needed descriptions of the current linguistic scene of Arabic language and can also serve as database to form projections on the evolution of Arabic in general.
