Problem Statement: The most used method to understand the complex structure of language in linguistics is to monitor the stages that the child experiences in the language development process. As a result, language development and language acquisition of children have become a concern for language studies. The related literature in Turkey indicates that there are many studies carried on Turkish language. However, the literature regarding the language acquisition of Turkish children is limited.. This study, carried out as supplementary for the previous studies aims to reveal the comprehension stages of Turkish children in terms of grammatical and morphological perspectives.
