The current research delves into the argument ellipsis (AE) phenomenon in Jordanian Arabic (JA), as exemplified by the omission of a predicate’s argument in a phonetic form but still amenable to semantic interpretation. Although AE has been intensively explored among East Asian languages and Hebrew, it received little academic attention among the different dialects of Arabic. This research presents the outcomes of a large-scale acceptability judgment test with 69 subjects and proves that the rate of acceptance of sentences with elided arguments by the native speakers of JA is as high as with non-elided sentences. Adopting a feature-based account with a Generative Syntax framework, the research proposes using a feature E on the little v head to achieve AE in JA. The research illuminates the interrelationship of AE and the rich agreement morphology in JA and feeds into a live debate in a cross-linguistic setting on how agreement and ellipsis interrelate. The evidence negates generalizations holding rich agreement patterns to block AE and presents instead how complicated morphological structures permit argument ellipsis and do not impede it. The research expands typological awareness of AE to include Semitic languages and sheds new light on syntactic parameters controlling variability of ellipsis effects across different language groups.
