This article is devoted to the study of the processes of development and dynamics, sources and ways of development of the political and social terminology of current Ukrainian language in the period of Ukraine’s independence – from 1991 to the present day. It is acknowledged that Ukrainian political and social terminology is a relatively stable and traditionally consolidated lexical and semantic system, which is in a state of uninterrupted development and progressive improvement. The development of terminology is determined by factors of a socio-political, functional and linguistic nature. Therefore, we understand a publicpolitical terminology as a system of differently named nominative units, specialised lexically (created or loan terms), semantically (generalised words that have acquired a nominological meaning) and phraseologically (newly created word-combinations of nominative character) for expressing the understanding of the sphere of public and industrial, political life of the nation. The illustrative material for the study was the textual content of the published and electronic media and the relevant lexicographic, political and legal sources. The article analyzes semantic changes of certain public and political names, in particular, changes in the semantics of terms due to the introduction of new values or replacement of semantics in lexemes with an ideological component by lexemes without an ideological component, use of obsolete terms, both new and long-standing, new and old lexical borrowings. A special place is given to jargonisms as an insignificant component of contemporary political discourse. It is noted that the assessment of new vocabulary is the main requirement for researchers to identify trends in the development or changes in the lexical and verbal norms of Ukrainian language.
