The purpose of this article is to characterize the word «merciful» in the Kazakh linguistic culture and identify its correspondences in the Russian language consciousness, research its linguistic fullness, as well as the identification of the linguistic and cultural specifics of the given language unit.

Representatives of a different lingvo cultural community (in this case, Russian), the perception of language units is not entirely adequate which is primarily due to the discrepancy between the lingvo cultural experience of the representatives of the Russian community compared to the Kazakh one. And in this regard, to present the studies of Kazakh language units in comparison with the Russian language ones is of great interest for comparative lingvo regional studies.

The word «merciful» is one of the most important vital reference points for a man and therefore naturally receives plural lexical and phraseological meanings and objectified by the key lexeme «mercy», sometimes the word itself objectified in the paremies, which contain key lexemes.
