Abstract
Lexeme analysis, including spatio-temporal definitions, indicates a universal process of categorizing human knowledge in objective reality. The article presents a synthesis of philosophical and linguistic approaches to the analysis of the category «space», via using encyclopedic, philosophical and cultural, metaphorical dictionaries for systemic and multilevel lexico-semantic research. Language confirms the existence in our heads of various structures of knowledge about the world, which are based on such a unit of mental information as a concept. Images, representations, concepts or their combinations pictures, gestalts, schemes, diagrams, propo-sitions, frames are formed in the process of perceiving the world, they are created as a result of cognition, reflect and synthesize human experience and reality meaningful in different types of activity with the world. The components of thematic groups of spatial relationships have been described in details and various ways. Nominative-semantic groups of the linguistic implementation of the category «space» have also been examined and systematized.
