Introduction: the aims and the importance of the study: regarding the importance of theobject marker “râ” as one of the components of persian sentences and its little investigation inaphasic persian speakers, we decided to study its usage in the speech of aphasic patients withagrammatic broca’s aphasia to know whether aphasic persian speakers use “râ” in comparisonto normal persian speakers. the agrammatic aphasics are known for not using function words(like the object marker “râ”).materials and methods: in this experimental-descriptive study, two groups were employed.in the first group, six persian children with broca’s aphasia participated as the experimentalgroup. the general linguistic capabilities of these patients were evaluated with the persianaphasic test by speech therapy specialists. in the second group, six persian-speaking normalpersons participated as the control group. two similar tests were administered to the aphasicand control groups, inspired by caplan et al. 's test, to know whether they use “râ”. as therewas a difference between the two groups, 1-way anova was utilized to see if this differencewas statistically significant. to analyze linguistic data, the approaches of garman, saffran,kolk, friedman, and dolfić and fabijanić were applied.results: while the control group produced “râ” in all cases, the aphasic group never used it.conclusion: it seems that using content words (like “nouns and verbs”) may be more vitalthan using function words (like “râ”).
