Fangfang", abstract = "This article is devoted to the empirical confirmation or refutation of an intuitively obvious assumption that more frequent words retain the inflectional type well, while less frequent words tend to change under the influence of analogy. This situation was confirmed in similar works during the study of verb unification process with an irregular declension in English and German: it was proved that the more frequent an irregular verb is, the more time it takes for it to transform into a regular one. However, the Russian language is arranged somewhat differently: there are several types of inflection in the verbal system of Russian language, each of which has its own peculiarities. The object of this study was the variability of forms in Secondary Imperfectives, and the goal was to reveal the patterns of evolution for the variation forms of a Verbal Paradigm Center. Specific tasks to be solved: highlighting the cases of norm change for 2 centuries; the obtaining of change of numerical characteristics for the most ‘conservative’ members of a paradigm, the suffix selection patterns. Based on the data from the Google Books, the frequency of the conservative form use concerning the so-called ‘redundant’ verbs was performed. Thus, the following hypothesis established: if the variability is observed in the compositional structure (according to Frege), then the main cognitive mechanism of evolution is the ‘regularization versus stability’; if a structure is non-compositional one, then the mechanism of a word semantic meaning delimitation is added, accompanied by the change in the frequencies of competing forms separately under the influence of a particular meaning relevance in society. A classification draft of a set of Secondary Imperfectives with the affix variation is given at the end of the article, depending on the nature of affix change and the factors affecting it (alternation of vowels in a root and l-epenteticum before an affix).", address = "51 Alexander Malinov blvd, Sofia, 1712, Bulgaria", booktitle = "5th International Multidisciplinary Scientific Conference on Social Sciences and Arts SGEM 2018", chapter = "ART {\&} HUMANITIES: Section Language {\&} Linguistics", doi = "10.5593/sgemsocial2018/3.6/S14.090", isbn = "978-619-7408-58-4", issn = "2367-5659", keywords = "Verb; Paradigm; Ngram; Google Books; Statistics; Speaking Norm", month = "26 August – 01 September, 2018", note = "5th International Multidisciplinary Scientific Conference on Social Sciences and Arts SGEM 2018, 26 August – 01 September, 2018", number = "3.6", organization = "Bulgarian Acad Sci; Acad Sci Czech Republ; Latvian Acad Sci; Polish Acad Sci; Russian Acad Sci; Serbian Acad Sci {\&} Arts; Slovak Acad Sci; Natl Acad Sci Ukraine; Natl Acad Sci Armenia; Sci Council Japan; World Acad Sci; European Acad Sci, Arts {\&} Letters; Ac", pages = "695-702", publisher = "STEF92 Technology", series = "International Multidisciplinary Scientific Conference on Social Sciences and Arts-SGEM", title = "{VARIATIVITY} {IN} {SUFFIXES} {OF} {SECONDARY} {IMPERFECTIVES} {IN} {RUSSIAN}. {COGNITIVE} {ASPECT}", type = "Proceedings Paper", url = "https://www.sgemsocial.org/index.php/jresearch-article?citekey=Galeev201814695702", volume = "18", year = "2018", }
