Abstract: Language is a complex process and its acquisition is hierarchical in nature. There is a critical age for the acquisition of each process. Some children with language impairment show a delay in the acquisition of these processes. There are many studies supporting the delay in children with language impairment. The purpose of the present study is to investigate the development of morphosyntax (conjunction, negation, case marker, tense and person-noun- gender marker) in children with specific language impairment.
