Abstract
The primary focus of the paper is on providing basic characteristics of subject-specific vocabulary classes and stratifying Aviation English vocabulary. Aviation English which serves for professional communication uses discipline-specific vocabulary which defines and transfers professional knowledge. The first part of the paper investigates the most commonly distinguished classes of lexis within the subject-specific vocabulary. They are stated to be terms, semi-technical vocabulary, professionalisms, professional slang and jargon, nomenclature names. Each class is presented in more detail in the second part of the paper. Peculiar features of every class of items are determined in order to enable differentiation from all other groups of lexis. The third part focuses on Aviation English vocabulary stratification. Taking into account the research already existing on the issue and having conducted its critical analysis as well as having thoroughly studied Aviation lexicographical issues and electronic-based aviation word lists, the authors present their view on Aviation English vocabulary stratification providing examples of lexis within each group. 6 groups of lexical items in Aviation English vocabulary are distinguished by the authors: 1) basic aviation concepts; 2) general scientific and interdisciplinary terms; 3) semi-technical vocabulary; 4) nomenclature names (nomens); 5) codes; 6) professional slang and jargon.
Highlights
Modern professional activity is based mainly on participants‘ interaction which presupposes verbal oral as well as written information exchange
To fully understand the linguistic features of Aviation English vocabulary and work out its stratification we have thoroughly studied the already existing linguistic research on the issues of language for specific purposes (LSP) vocabulary, the variety of its classes and categories
Modern aviation vocabulary is subject to the general law of language: its formation is a complex of quantitative growth and qualitative change, it is a system in motion. It covers the names of aviation concepts that appeared before, derives from other languages those elements which it lacks, adding new, those that relate to concepts that have just emerged (Karaban, 2004, p. 17)
Summary
Modern professional activity is based mainly on participants‘ interaction which presupposes verbal oral as well as written information exchange. Different professional spheres have their specific subsets of language which provide communication of its specialists and transfer of special professional knowledge. Subject-specific vocabulary is the core of such a language subset which defines, forms and transfers professional knowledge about objects, processes and phenomena of professional activity. It reflects scientific, technical, economic and social knowledge and is contrasted to general vocabulary. The boundary between these two classes of vocabulary is rather vague since one glossary item can be used both in everyday general communication as well as in a special sphere of knowledge and activity. The objective of this paper is to present Aviation English vocabulary stratification and define classes of Aviation English lexical items on the basis of their semantic and functional characteristics
