Essential aspects of formation of terminological thesaurus in the field of aluminium industry are considered in the article. It is known that such dictionaries are usually ranked depending on the sphere of their activity. They may include technical dictionaries, phraseological dictionaries, dictionaries of synonyms, polytechnic dictionaries, special dictionaries in different directions, etc. This process of thesaurus formation not only ensures the integrity of the system, but also provides access to its content.

The article examines the state and directions of development of modern Kazakh lexicography. The goals, objectives and possibilities of modern branches of lexicography are determined; the scientific-theoretical and practical foundations of compiling dictionaries are described. The development of the theory and practice of lexicography is due to such needs as the recognition of lexicography as a separate area of linguistics, the development of a theoretical basis for the creation of dictionaries, a general typology of dictionaries, the definition of the macro - and microstructure of dictionaries. Therefore, the purpose of this article is to summarize the experience of Kazakh lexicography, to identify its general theoretical problems, directions of development, to show its place in linguistic science. The study used a descriptive method, analysis and synthesis methods. A brief overview of scientific works is made, which study general theoretical and practical problems of Kazakh lexicography, research on the history of Kazakh lexicography, as well as works that consider the experience and scientific foundations of compiling dictionaries. The authors note the importance of the theory of lexicography in creating dictionaries, improving their quality, choosing the basic principles when sorting vocabulary units in a dictionary, the peculiarities of their functioning, the quantitative and qualitative composition of linguistic units to be included in the corresponding type of dictionary according to the subject of research, denote the theoretical and practical problems of Kazakh lexicography, scientific and theoretical foundations for creating dictionaries of the Kazakh language, determine the scientific, theoretical and practically applied aspects of modern lexicography as a science of language. Pointing to the importance of studying the scientific foundations of compiling dictionaries, their composition and structural features, both from a purely scientific point of view, and from the point of view of the implementation of state programs aimed at the development of the Kazakh language, the authors of the article conclude that the patterns and quality of compiling dictionaries directly depend on the basic functions of the language in modern society. The state of affairs in modern lexicography makes it possible to talk about the allocation of general lexicography, which studies the properties inherent in any dictionary, and particular sections of lexicography (educational, terminological, onomastic, etc.). General lexicography should establish common (or statistically dominant) features of all dictionaries using typology, as well as explore the general patterns of functioning and use of dictionaries. Private lexicography should contain sections that study the internal structure of this type of dictionary and methods for its creation; history of this type of dictionary; purpose and addressee of this type of dictionary. Therefore, experts in the field of lexicography believe that the prospects for the further development of lexicography are seen in the improvement of existing and creation of new types of dictionaries, the emergence of complex dictionaries and the computerization of lexicographic activities.
