The question of the synonymic community of antonyms as a part of some structures
The problem of semantic contiguity of synonyms and antonyms is studied. Synonymous and an- tonymous paradigms form a common lexical-semantic group. Traditional definitions of synonyms and antonyms show that they have the property of interchangeability, therefore, can be used in the same context. The cases when the word is replaced by another word opposite in the meaning and the sense of the expression remains the same are the object of research. Cases when lexemes „ bog’ - ‘chert’ can be interchangeable in equal contexts in expressions ‘bog s nim’ - ‘chert s nim’ without sense change are examined. The weakened nominative value and semantic proximity of synonyms and antonyms become the mutual substitution reason lexically opposite words in expressions at sense preservation. One can face the analyzed phenomenon in the non-free lexical expressions or interjectional structures, when words do not form independent nominative meaning and consequently, cannot express semantic opposi- tion.
