Term Formation in the Lexical-Semantic Field “Chemical Engineering” in Modern English: Structural and Derivational Aspects

Background. In modern linguistics, research is being carried out on the methods of term formation in the lexical-semantic fields of various spheres of human activity. The purpose of the article is to study term formation in modern English in the lexical-semantic field “chemical engineering” based on structural and derivational aspects. The structural aspect means component analysis, which allows us to identify the number of special lexical units in a terminological combination. Materials and methods. A sample of special lexical units (363) from English-language articles in the chemical industry is presented as material for the study. Descriptive, structural, typological, as well as the method of component analysis were used to study the material. Results. The most common and less common structural models have been identified based on the partial compatibility of components, as well as the lexical length of special lexical units, i.e. the number of components in a terminological combination. The morphological features of special lexical units have been determined. Analysis of grammatical derivation allowed us to identify linear models, including affixation and compounding, as well as non-linear models represented by abbreviations, for example, abbreviations, combinations with abbreviations, nomenclature units, combinations with nomenclature units and word mergers with truncation of word stems. The semantic aspect of the analysis of special lexical units allowed us to identify a few anthroponyms, as well as units with internal predication. Scope of application of the results. The results of the study can be used for further research on term formation in lexical-semantic fields.
