The article is devoted to the study of the current topic of modern communication– virtual language personality, and the description of lexical and semantic features of virtual language personality in Internet communication. The issue of dynamic changes in the Kazakh vocabulary introduced through Internet communication has become especially relevant in recent years. The research work began with a review of the research of domestic and foreign scientists, the features and main trends were described. During the review of scientific papers analyzing the discourse of the social network and its text, the fundamental concepts were identified and the necessary conclusions were drawn, which guided us. The purpose of the study Is to consider the set of lexical and semantic properties of social network usages. The article notes that the main feature of communication in Kazakh-speaking social networks is the replacement of a real participant by a participant in virtual communication. We have done analysis of the structure, lexical and grammatical characteristics of Kazakh texts collected from social networks. The features of the texts of the discourse of social networks were described. It is mentioned that texts in social networks are not a source of knowledge, they are news or entertainment information, and accordingly they should have brief but rich information, the information in the text is transmitted not only by writing letters, but also by pictures, audio and video recordings. Examples from Facebook and WhatsApp networks were given as research materials. The study revealed the use of Facebook language terms in Kazakh texts, an increase in the activity of foreign words, a lexical-syntactic combination of foreign and native words, a combination of words without a lexical combination, etc. As a result, on the basis of the collected materials, grammatical (morphological, syntactic) features of Kazakh texts in the social network were divided into groups and a linguistic analysis was carried out. In modern public consciousness, linguistic research has become relevant, defining the linguistic image of a social network as a means of implementing linguistic communication. In this regard, it is very important to improve the language skills of network users.
