Agrammatism is a frequent sequela of Broca's aphasia that manifests itself in omission and / or substitution of the grammatical morphemes in spontaneous and constrained speech. This study investigated question production as well as production and comprehension of grammatical morphemes corresponding to tense, agreement, and negation in Arabic Jordanian agrammatism. The data of this study was composed of different experiments that had separate scoring and data analysis procedures specified for each experimental task. Experiment 1 (sentence elicitation and repetition) was used to examine production of Wh and yes/no questions. Experiment 2 examined grammatical morphemes corresponding to tense, agreement, and negation through sentence completion task , and experiment 3 examined comprehension of tense and agreement through grammaticality judgment . Results of this study indicated near ceiling performance of control subjects on question production, question repetition, functional category production, and grammaticality judgment tasks. In contrast, individuals with agrammatism demonstrated deficits across each of these tasks. Production of yes/no questions was much better preserved than Wh-questions. However, there was no statistical difference between the production of argument Wh-questions and adjunct Wh-questions. The results of the question repetition task for agrammatic group revealed that the production of matrix questions repetition was better than that of embedded questions repetition. Sentence completion task results revealed dissociation among functional categories, that is, tense, agreement, and negation were not equally impaired in patients' production. The production of agreement inflections and negation production was much better than that of tense inflections. The results of the grammaticality judgment task revealed that participants with agrammatism had more errors than the control group. However, there was no significant difference in participants’ sensitivity between tense and agreement violations. A thorough discussion of each one of these findings was discussed to conclude that TPH is adequate explanation to deal with our data. The findings of the structured tasks in this study were compatible with TPH states that the syntactic tree is pruned from the tense node and up, leaving the lower nodes such as agreement and negation nodes with less impairment. The resulting data thus provides a good addition to the controversy about the universal and language specific characteristics of agrammatism.
