The Concept of Invariant in Semantics
The article is devoted to the study of problems of variability in language, its subject is the concept of invariant / variant in relation to the lexeme. The author demonstrates that the concept of invariant / variant in Russian and foreign linguistics is controversial and debatable: ambiguously understood as the content of the entity (invariants) and the samples (variants) and their ratio. The research reveals that consistent application of the idea of invariant value in relation to the lexeme leads to the idea that the invariant is not compulsory phenomenon of the language system.
