Синонімія та варіантність в українській науково-технічній термінології

Thesis for the Scholarly Degree of Candidate of Philology, Speciality 10.02.01 - Ukrainian Language. - The Ivan Franko National University in Lviv, 2009.

The thesis highlights phenomena of synonymy and variance in the Ukrainian scientific and technical terminology. It is the first attempt of comprehensive analysis of synonymy and variance at different levels (phonetic, lexical, word-building, morphological, syntactic). The research analyzes reasons for appearance of synonymic and variant terms among authentic and foreign names, traces development of this phenomena in the Ukrainian scientific and technical terminology during the 20th - beginning of the 21st centuries and suggests the ways of avoiding unjustified synonymic and variant names of scientific phenomena.

The first chapter provides theoretical basis of the synonymy and variance research in the field of term lexis. Various viewpoints of the linguists on this phenomenon are analyzed starting from its absolute rejection as negative and abundant phenomena in scientific and technical terminology to positive evaluation of synonymy and variants that demonstrate constant development of terminological systems. The synonymic and variant terms are classified according to the language levels, the reasons and prospects of the phenomenon of synonyms and variants is clarified.

The second chapter focuses on the analysis of synonyms at the lexical level in the Ukrainian scientific and technical terminology. Five groups of term lexical synonyms are distinguished: borrowed term - authentic analogue, terms with international components and their Ukrainian correspondents, hybrid terms and their native equivalents, lexical synonyms of the Ukrainian origin and lexical foreign synonyms. The reasons for appearance of lexical level synonymic terms are studied and the ways to avoid unjustified parallel names of this type are suggested.

The third chapter analyzes synonymy at the grammatical level in the Ukrainian scientific and technical terminology. Among synonyms of this level two large groups are distinguished: word-building synonyms (homo-based word-building synonyms, hetero-based word-building synonyms, word-building synonymy is reflected - derivatives of word-building synonyms); syntactic synonyms (syntactic synonyms proper - synonymic word-combinations and synonymic terms of various structures). Parallels of this type are mostly justified, and it reflects features and tendencies of this phenomenon in the national language, however, in cases when suggested names differ in meanings, they should be considered different words and should not be put into one synonymic row or they should be fixed as one normative term.

The fourth chapter concentrates on the analysis of variant terms of various language levels (phonetic, word-building, morphological, syntactic) which are actively functioning both among native terms and foreign ones. Variant terms are less numerous in terminology as their existence mostly shows the initial stage of national terminology formation. However, variant terms which were removed from the dictionaries in the 30s of the previous centuries now are re-introduced in the dictionaries for re-approbation that is the most important reason for the functioning of variant terms in the Ukrainian scientific and technical terminology.

The research made it possible to determine peculiarities of synonymy and variance in the term lexis and has shown that these phenomena are inseparable features of the development of any terminological system as a subsystem of the literary language.

Key words: Ukrainian scientific and technical terminology, synonymic terms, variant terms, terminological system.
