The article contains an overview of new trends in Ukrainian literary and colloquial language development in historical retrospect and dynamics. In particular, changes in the lexical structure of language, new phenomena in word formation, morphology and syntax, innovative shifts in styles, etc., in the context of communicative strategies and tactics, rhetorical, stylistic, and linguistic norms and techniques adopted in various spheres of communication are considered. The article is aimed at forming ideas and gaining knowledge in the field of the theory of the modern Ukrainian language in those sections that are distinguished by the greatest significance of the theoretical approach (grammar, syntax), as well as skills and abilities in those parts that require an applied application (culture of oral and written communication, stylistics, rhetoric, genre studies, the principles of spelling).
