This study presents a comparative syntactic analysis of verb conjugation patterns and agreement markers in Baghdad Arabic and Basra Arabic, with particular attention to regional linguistic divergence. Drawing on a morphosyntactic framework, the research investigates how person, number, gender, and tense aspect mood (TAM) categories are encoded in the two dialects, and how subject verb agreement is realized under different word orders, especially subject verb (SV) and verb subject (VS) constructions. The study is motivated by the need to better understand intra-Iraqi dialectal variation and the extent to which grammatical distinctions reflect broader sociolinguistic and historical processes. The research adopts a qualitative comparative design based on descriptive analysis of dialectal forms. Data were collected from native-speaker elicitation, spoken usage examples, and available dialectal sources, and then categorized according to conjugational paradigm and agreement behavior. The analysis shows that while Baghdad Arabic and Basra Arabic share a common Arabic grammatical foundation, they differ in several morphosyntactic respects, including the distribution of verbal affixes, the realization of agreement markers, and the extent of agreement reduction in VS structures. Baghdad Arabic exhibits some innovative forms and levelling tendencies, whereas Basra Arabic retains certain conservative features and distinct regional realizations. The findings indicate that verb conjugation and agreement in both dialects are systematically structured but not identical, with divergence shaped by regional identity, contact influences, and historical continuity. The study contributes to Arabic dialectology by offering a focused comparison of two major Iraqi urban varieties and by demonstrating how morphosyntactic variation serves as a marker of linguistic identity.
