Abstract: In this paper, the authors consider in detail the current state of the conceptual dictionary of sociology. The phenomenon of leisure practices is chosen as the object of research. And the subject of the study is the conceptualization of the concept of "leisure practices" in modern sociology. The authors consider in detail the formation of leisure in social and humanitarian scientific knowledge, starting with ancient philosophical ideas. The evolution of leisure practices from ancient forms to modern varieties is traced. Classical and modern works of foreign and domestic authors relevant to the subject are chosen as theoretical bases. It is noted that today leisure practices are considered mainly through the prism of three methodological approaches: symbolic interactionism, structural functionalism and neo-Marxism. The authors argumentatively show that during their development leisure practices occupy an important place in the structure of human activity, since they are one of the most effective ways of personal development, forming its spiritual and physical qualities. Leisure needs are firmly embedded in the value system of all social groups, while the progressive development of world civilization suggests new options and versions of organizing and spending free time. As a special contribution of the topics raised by the authors of this study for the modern sociological discourse, the necessity of continuous research of leisure practices is laid due to their dynamic nature and because of their determinism by contextual realities. The author presents his own concept of leisure practices, taking into account their essential characteristics and allowing to go beyond the one-sided understanding of leisure, for example, such widespread as identical to free time.
