Objective: How the two languages grow and differ in early childhood is a key topic of discussion about language acquisition in bilinguals. The present research compared the morphosyntactic growth of Urdu-only speakers versus bilingual Urdu-English speakers between the ages of 4-6 years. The current research also looked at how much age influences morphosyntactic development and the relationship between multilingual children's morphosyntactic growth and exposure to second languages. Methods: This cross-sectional research used the test of early grammatical impairment (TEGI) at Mayo Hospital over the period of 1 month and a questionnaire on language history to assess how well monolingual and bilingual individuals performed on English morphosyntactic indicators. The groups were contrasted using an independent sample t-test. Results:The findings showed that (1) monolingual individuals performed better than their bilingual counterparts in using English morphosyntactic cues, (2) participants aged 5 performed better than those aged 4, indicating an age effect, and (3) there was a positive link between exposure to second languages and TEGI scores. Conclusions:The present research sheds light on how bilingual children's exposure to L2 influences how their L2 develops grammatical markers.
