This article considers the semantic derivation of applied geometry terms in Kazakh language. The actuality of the topic is conditioned by the fact that in spite of rather extensive research in the field of semantic derivation of both lexicon in general and terms of various sciences, the problem of semantic derivation in the sphere of terms of applied geometry in Kazakh language has not been devoted to special works. The aim of our research is to study the terms-metaphors of applied geometry in terms of semantic derivation, to determine the change in the scope of meaning of applied geometry terms depending on their transition from the common language to the branch terminology, and vice versa the transition of terms into the common language. The article defines the term «semantic derivation» and briefly describes the history of the development of this phenomenon in linguistics. Special attention is paid to the modern consideration of the issue of semantic derivation from the perspective of cognitive linguistics. The perspective of this study lies in the fact that these metaphorical terms are able to express the connection between the language of the nation and the language of science by means of certain images and associations that are inherent of metaphor. As a result of research in this area, it was concluded that semantic derivation is the volume of the most productive way of word formation in the field of applied geometry terms. Cognitive approach to semantic derivation of applied geometry terms, which is based on the idea that the human conceptual system is metaphorical in its essence and is reflected not only in language, but also in thinking processes.
