The article is dedicated to the characteristics of the “life/death” explication in prose narratives of Slavic folklore in particular. The authors were able to study and understand the archaic beliefs immanent for the ancient Slavs through researching the words and fairy-tale images that personified life and death in this type of literature. The relevance of this topic derives from the insufficiency in the research of representation of “life/death” binary opposition in various languages and in folk prose narratives. This study contributes to understanding the attitude towards this binary opposition in the distant past and its impact on the modern people’s attitude towards life and death. The purpose of the study is to investigate the binary opposition and its perception among people through folk prose narratives. The authors chose an integrated methodological approach for researching this issue. It helps to comprehensively analyse the attitude towards the binary opposition. The study successfully used the methodology and techniques applied in humanities, primarily in philology and philosophy. While researching the topic the authors found out that in some cases this binary opposition is perceived figuratively, and in others cases it is dramatically diametrical, which is reflected in fairy tales, proverbs, curses, etc.
