THE TERMINOLOGICAL UNITS IN THE FIELD OF LINGUISTICS AND DIDACTICS ACCORDING TO THEIR STRUCTURE

The article deals with the characterization of terminological units from the aspects of lexico-semantic structures which are specific for all their semantic features by means of linguistic approaches. The main semantic properties of terminological units of language didactics can be studied by means of linguistic analysis. The criteria could be defined as following: 1) terms which are formed by lexico-semantic ways; 2) polysemantic terms; 3) terms synonyms; 4) terms antonyms.

Semantic changes in the formation of terms owing to their polysemantic features and relationships of meanings which may be found through the context. The main processes of formation and dynamic development of the terminological system of this science have been investigated owing to materials of English, Russian and Uzbek languages. However, it is important to define the role of national context in the development of   the terminology system of language didactics by help of cross-cultural analysis, existing problems of comparative study of terminology, and searching corresponding equivalents of terms in Russian and Uzbek languages.

Semantic development of a term improves general meaning belonging to a term and changes according to its forms. However, sphere functioning of a term which connects with constantly developing scientific opinions for improving notions   in the field of linguistics.

   Among the terms there are number of absolute synonyms, as is known that it is possible to remove doubling in the subsystem or by the way of semantic differentiation for the nomination of new conceptions. Differentiation of synonymic microsystem as opposite process of fusing separate terminological microsystem, so another microsystem which serves for determinization of developing special vocabulary in all its historical sections. As a result of it there occurs the fusion of lexico-semantic variants of a single term, introduced in the integrating subsystem, but another subsystem which combines all similarity features of components of the lexical unit, transfers into polysemantic lexical unit.

The aim of the research is to improve the necessity of defining the main factors and sources of the formation and dynamic development terminological units of this science and their usage in the different socio-cultural contexts, including specific features and differences in the expansion of terms of the language didactics according corresponding culture.
