In the article the problem of diglossia in the Christmas carol of Hutsuls based on the interaction of Christian and heathen elements is discussed. The sources of the study are the texts of the Christmas carol which were recorded in the village of Kryvorivnia (Verkhovyna district, Ivano-Frankivsk region). These texts are analyzed in a diachronic section: the phenomena of Christianization and dual-faith and their implementation in the Christmas carol tradition of Hutsuls are considered. Based on the content and formal analysis of the text of the Christmas carol, the main motifs and images are singled out. It is emphasized that in these motifs and images of diglossia features are realized. The article outlines the main ideological principles, embodied in Christmas carols, and analyzes the main thematic features of the calendar ritual folklore of a winter cycle. The diﬀ erentiation of terminology, content and formal features of church carols and carols was also conducted. Based on the results of the content analysis of the text content of the carolytic tradition, its main functions are determined. The conclusions state that the modern Christmas carol tradition of Hutsuls reveals a syncretic completion, which combines Christian and pagan elements, and diglossia features most often appear on the content level. Descriptive and comparative methods, as well as elements of discourse analysis, were used for the study.
