The language acquisition process can vary from child to child depending on various situations; however, most typically developing children are often found following a biological timetable to learn different aspects and grammatical structures of their ambient language. Various research has been conducted worldwide to investigate the fascinating process of children's language acquisition. This poster examined some morphological and syntactic aspects of a 35-month-old Bengali-speaking girl's children's data.
