This book is a syn-chronic descriptive account and analysis of the Tihami Yemeni Arabic (hereafter TYA) spoken in Zabid, an important city in Hodeidah province and Tihamah of Yemen. It is confined to provide a full, unified descriptive analysis of the (root-and-pattern) morphology of nouns and adjectives and the plural formation assigned to them using the two plural techniques so-called revowelling and affixation. It also provides morphosyntactic representations of gender-number agreement and definiteness agreement between nouns and attributive adjectives. It has 6 chapters: First: Introduction, Second: Structure of Nouns in TYA, Third: Structure of Adjectives in TYA, Fourth: Broken Plural vs. Sound Plural assignments in TYA: Revowelling vs. Affixation, Fifth: Agreement between nouns and attributive adjectives in TYA, and Sixth: Summary and Conclusion and Recommendations for Further Studies. By the deletion of TYA unique linguistic features represented in its pausal /u/ or over-generalized nominative case /u/, this book will have a global impact in case of the study of other modern Arabic dialects and contribute to the field of Semitic as well as Arabic Linguistics.
