Methodology of the Tajik language is a subject that provides information about the different methods, techniques, ways and approaches to teaching the native language. It necessarily relies on the theoretical and practical foundations of linguistics. And, first of all, it is aimed at the national upbringing of the younger generation and, on this basis, the formation of the foundations of a perfect human being. The methods of studying each chapter of the plan clearly show the connection and clearly define the nature of the individual components of each chapter of the Tajik grammar. That is why language is known as a means of communication between people. It is noted that language is a means of communication, the existence of relationships in production. Thus, one of the main tasks and objectives of the language methodology course is to teach the teacher how to teach each chapter of the mother tongue plan and to provide practical assistance to his work in the field of education and upbringing of children. They acquire basic skills in ethics, work and life of society, attitude to the environment, information about nature, and, of course, their thinking and worldview develops. Hence, students of Tajik schools learn in their native language, the modern Tajik literary language, as it is the language of the Tajik nation and is one of the cultural forms of the Tajik people and an indicator of its long history.
