Children with developmental language disorder (DLD) experience difficulties with a range of morphosyntactic skills, particularly with tense and subject - verb agreement. Many studies have examined verb-morphology production in children with DLD. We extend this line of research by profiling verb-morphology comprehension in 67 monolingual Saudi Arabic-speaking children, comprising 33 with DLD (M = 61 months, SD = 10.70), and 34 age-matched typically developing (TD) children (M = 63 months, SD = 8.94). Children completed a novel picture selection task developed to assess their comprehension of verb tense, gender agreement, and number agreement. Children with DLD scored significantly lower than TD children on the verb morphology comprehension task. They showed greater difficulty identifying verb tense forms, particularly future tense. They also demonstrated lower accuracy in identifying subject-verb agreement in general, with specific difficulty in comprehending masculine verbs, and singular verbs. These findings were compared with production verb-morphology data from previous Arabic studies. Overall, this study highlights the challenges experienced by Arabic-speaking children with DLD in comprehending verb morphology, particularly tense and subject-verb agreement inflections. These findings can be used to tailor appropriate assessment designs and interventions for an Arabic-speaking DLD population.
