Abstract
<p>The article offers the description of a modern experiment, which gives the possibility of complex information extraction about the cognitive structure of the linguistic evolution of Language Standart (Norm). The study was conducted using the Google Books Corpus, which provides unprecedented opportunities for linguistic studies. The purpose of the experiment was to identify the patterns of competing forms evolution within the center of the verbal paradigm (3Sg and 3Pl) on the basis of the data concerning the frequency of their use. The study was conducted on the material of excess verb forms with the variability of <em>a/o</em> vowels in a root (<em>обусловливать</em>/<em>обуславливать</em>). The graphs for variable word form competition clearly illustrate that the process of norm change consists of stages, each of which has numerical characteristics of two competing word form use. The chronological frameworks for an inflectional model change are established with the accuracy of up to 10 years. The graphs obtained as the result of the experiment make it possible to conclude that almost half of the verbs were not variative, although they previously considered. During the discussion of the obtained empirical data, a conclusion is made about the morphemic structure of a word, in which a root vowel changes. Possessing the information about similar processes in other verb paradigms, researchers are able to predict a possible change of inflectional models in the future and, as a consequence, the fixing of a new norm in lexicographical, orthographic and orthoepic sources.</p><p> </p>
Highlights
The significance of the frequency for the morphological system of verbs has been studied very actively in recent years
Using Ngram Viewer service, which allows to create graphs concerning the frequency of word usage using the material of the texts from the Russian-speaking part of the Google Books corpus, the main interaction models of particular two verbs are described
Results of the study In the framework of a quantitative study of an excessive verbal paradigm structure and the "conservatism" of its individual parts, 68 pairs of verbal paradigms were analyzed with the variability of the vowels "o/a" in the root
Summary
The significance of the frequency for the morphological system of verbs has been studied very actively in recent years. By the actual data these studies confirmed 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. Taking into account the fact that Russian language is inflectional, a special attention must be paid to the various morphological processes accompanying the inflectional paradigmatics. Such processes are actively studied by modern experts in Russian language (Zagidulina et al, (2016); Varlamova et al, (2014)). The object of the study is represented by variable verbal forms with the variability of the vowels a/o and the root (обусловливать/обуславливать) according to the data of several modern dictionaries and collections (Graudina, 2004; Gorbachevich, 2009), as well as according to own files of examples compiled by the authors, with the total volume of about 68 units
