Classification of language didactic terms in line with their lexico-semantic structure

The article deals with the characterization of terminological units from the aspects of lexicosemantic structures which are specific for all their semantic features due to the means of linguistic approaches. The main semantic properties of terminological units of language didactics can be studied using 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 may be found through the context. The main processes of formation and dynamic development of the terminological system of this science have been investigated thanks to materials of the English, Russian and Uzbek languages. However, it is important to define the role of a national context in the development of the terminology system of language didactics undertaking cross-cultural analysis, existing problems of comparative study of terminology, and searching relevant terms in the Russian and Uzbek languages.
Semantic development of a term improves general meaning belonging to a term and changes according to its forms. However, functioning sphere of a term connects constantly developing scientific opinions for improving notions in the field of linguistics.
There are a number of absolute synonyms among terms, given that it is possible to remove doubling in the subsystem or using semantic differentiation for the nomination of new conceptions. Differentiation of synonymic microsystem as opposite process of fusing a separate terminological micro-system, so another microsystem serves for determining a 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 poly-semantic 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 of terminological units of this science and their usage in different socio-cultural contexts, including specific features and differences in the expansion of terms of the language didactics according to corresponding culture.
