The article discusses some linguistic examples never previously presented in the form of full texts. Taken from lectures and spoken communications examples illustrate the explanatory potential of the ingenious linguistic theory of a unique but unfortunately little-known Russian linguist G. P. Melʻnikov. The purpose of the research is to update and represent for linguistic professional community the central idea of G. P. Melʻnikov’s conception – the idea of explaining the phenomena of one level of language by facts of the other levels. The authors have based their work on the systemic method of linguistic theory constructing and the explored by G. P. Melʻnikov doctrine of external and internal determinants of languages. The results can be used in linguistic typology and theoretical linguistics for explanation of a wide range of language phenomena.
