In this work, the author has based his practical derivations on a longitudinal case study of " the Development of Kurdish Syntax" in which he has investigated the developmental stages of syntax which may shed light on theories of first language Acquisition such as Chomsky's UG. He has observed his child's verbal behaviors, such as silent story telling and story making, repetition of adult utterances and specifically the production of novel items to revisit the strategies children use during the process of first language acquisition. The findings of this research have implications for language teaching at three levels of Approach, Method, and Technique. The case of the research who was the son of the researcher, was observed up to 37 months of age through the methodology of 'Naturalistic Focused Observation'.
