Plot invariant and variability in linguistics, literature and theory of translation
This article deals with the study of the plot invariant and its variability that occurs on the level of the linguistic structure of texts. The material of research is based on Middle English folklore texts. The author tries to show the notion of variation as a process taking into account literature and linguistic stability and variability of the folk texts. Becoming more resultative even in the theory of translation, the concept of invariant for an interpreter is the idea that should remain unchanged and understood as information to be passed on, while an expressed idea is becoming a variant already.
