Introduction. The lexical parallels in question are units of the active vocabulary. Being inherently somatisms, the correlates over time have come to denote language as a sign system and speech. The study of the Germanic-Slavic lexical parallels Zunge – language in the comparative-historical perspective allows us to identify their in-herent structural-linguistic changes and semantic transformations in the diachronic perspective. Purpose: to ex-plore Germanic-Slavic lexical parallels in etymological, structural-linguistic and lexical-semantic aspects, involv-ing etymological and linguocultural data. Materials and methods. The theoretical basis of the work was the sci-entific data recorded in lexicographic sources of domestic and foreign linguists. In the course of research work, methods of continuous sampling, generalization, comparison and component analysis were used. Discussion and results. The first written evidence of Zunge in the Germanic language field dates back to the 8th century, in the Slavic – to the 10th century. Russian and foreign linguists have not developed a common point of view on the reconstruction of the Indo-European substrate of the Proto-Slavic base *e̜zykъ and the Germanic base *tungōn. The semantic scope of the Russian and German lexemes in question is different in width. In the course of the study a high quantitativity of the implementation of Germanic-Slavic correlates Zunge – language as components of phytonyms and zoonyms was noted. The analysis of lexical parallels is given with the involve-ment of phraseological data. Conclusion. The study of the Germanic-Slavic parallels Zunge – language re-vealed both common and different characteristics for them in the aspect of their functional-language and lexi-cal-semantic features. The importance of studying the Germanic-Slavic parallels in determining the nature and chronology of the ways of penetration of lexical units from one language into another is highlighted.
