... elopment are described. Special attention is payed to the modeling of self-organization process of word-formation means from the perspective of synergetic science. Applying the principles of synergetic methodology within linguistic researches is regarded as a new tool for studying both the language system in general and its subsystems in particular. Introduction. The synergetics notion of self-organization and the following principle of circularity in living-matter organization perform a great role in understanding essence and functions of the language as a natural (mental and biological) sign system. One does not wonder that the problem of language systemacy, having drawn little interest of theorists at the end of the 20th century, attracts today linguists again [1-8], which conditions the relevance of our research. From A. E. Kibrik's perspective, "the current linguistics is getting close to the limit when the autonomic descriptive approach becomes out-of-date, <...> linguistics begins to operate with quite involved complex language objects each of which consists of the infinite component set" [3, p. 103-104]. A great potential for describing mechanisms of self-regulation of word-formation means in the language system is provided by synergetics-a self-organization theory aimed at "discovering common self-organization and development laws and at applying respective designed models widely" [4, p. 99-113]. Synergetics studies common self-organization and development principles of different complex systems explaining the appropriateness of existence of transient states, non-linear and unconventional decisions in terms of solving certain tasks [9]. Applying methods and principles of the synergetic paradigms as the most optimal way for describing evolutionary processes in the language makes the relevance of the study. The specific topic of the article is modeling of the self-organization process of word-formation means from the perspective of the linguo-synergetic conception. The research object of the article is word-formation suffixes of abstract nouns in the German language. The subject matter is covering the diachronic aspects of word-formation system in the German language. Results of the research. Language develops continuously. In the vocabulary of Old Germanic languages both abstract words and abstractness suffixes are widely known to have been secondary and later formations. Having appeared in the sphere of separate types of noun declension, abstract vocabulary was originally produced by stem-forming suffixes each of which had its own class of lexical units and was (as it is believed) a class indicator. The later appearance of more abstract nouns within these declension types proves the supposition of stem-forming-suffix semantics having served as a major factor by paradigmatic producing of the analyzed lexical layer. Consequently, primary abstract
