Abstract: The article deals with history and condition of geographical terminology of Crimean Tatar language, the brief overview of Crimean Tatar scientific terminology development is given. The work also indicates the range of sources that can be useful in the study of this problem. This article aims to study and to describe the principal periods of Crimean Tatar scientific terminology development, geographical one in particular, also to determine the perspective of its development. The subject of the study is geographical terms and adjacent nomenclature. The methodological and theoretical basis of the research were works of G.H. Bukharova, Z.S. Kamaletdinova, G.K. Konkashpaeva, I. Kerimova, O.D. Rustemova, and others.  In this work were used a descriptive and historical-comparative method. To date, geographical terminology in the Crimean Tatar language has not been the subject of special linguistic studies. The importance of the study of this terminological system is emphasized by the need for historical analysis, review, and systematization of geographical terminology, as well as the need to streamline the processes of term formation for today and in the future. It is impossible to characterize the current state and identify the prospects for the development of geographical terminology in the Crimean Tatar language without assessing what contribution scientists have made in the past to the development of this problem and what significance their positions had for their time. This explains the need for the historical digression – the definition and study of the origins of geographical terminology, the main stages of development of the term system.
