Rainbow symbolism in the paremiological fund of the Russian and Chuvash languages: cognitive and lingua-cultural analysis

This article presents a comparative analysis of rainbow symbolism in the paremiological fund of the Russian and Chuvash languages. The rainbow is considered as an iconic natural phenomenon representing transcendental, ethical and sacred meanings. The research is carried out in line with cognitive semantics and lingua-culturology using ethno-linguistic data. It has been established that in both linguistic cultures, the rainbow acts as a sign of a boundary between worlds, a sign of divine warning as well as an axiological marker of conditions necessary to achieve harmony.
