Posobchuk O. Structural Peculiarities of Prepositional Word Equivalents in Ukrainian, German and Spanish.

The thesis focuses on a research of structural peculiarities of Ukrainian, German and Spanish prepositional word equivalents which are a group of interlevel language units with prepositional function. In General Linguistics, facts of a single language are hardly a representative phenomenon. Therefore, the study insists on the necessity of examining interlevel language units as a complex problem in a group of remotely related languages.The paper takes stock of various types of connections between the language units in question and points to open issues and desiderata for future research in this area. For further investigation, it seems reasonable to look at other groups of interlevel units of world languages, which will cast light on channels of language system change.
