Introduction. Researchers of media discourse, along with the positive aspects of the development of modern Ukrainian literary language in the media, point to the decline of media speech culture. The purpose of the article is to record examples of Russification and language negligence in online publications, to provide practical recommendations for improving the speech culture of journalists. Results. Interferems and Russianisms in online mass media are studied. The source base of the study was journalistic texts of online publications of national and regional significance ("Ukrainian Truth", "Doba").The analysis of the revealed deviations from lexical norm is carried out, the basic erroneously dangerous places are specified. It is proved that a common type of lexical errors in the language of the media - interferems and Russianisms. According to the classification of interference, in the analyzed online publications can be divided into two groups of such non-normative units. The first group includes single tokens-interferems. They form a small system of representatives. The second group of formations of interferomic character consists of non-normative combinations of several tokens. In the process of linguistic examination of journalistic materials, non-normative tokens-Russianisms (a word or phrase borrowed from the Russian language or built on the model of Russian words and expressions) were revealed. The inappropriateness of using nouns with the suffix -k- to denote an action in appropriate contexts is characterized, instead the analyzed materials distribute such formations. A number of extra- and intralinguistic factors have been identified, which have led to the spread of Ukrainian Russian-language interference elements in speech. The main extralinguistic reasons are the following: living in Ukraine a significant number of people who only understand the Ukrainian language, but do not speak it; knowledge of the majority of Ukrainian citizens in both languages - Ukrainian and Russian; improper knowledge of Ukrainian speakers of its norms; poor vocabulary of speakers; imperfect language policy in the state; lack of an effective mechanism for implementing the Law on Languages. The main intralinguistic factors are the typological affinity of the East Slavic languages and the formal (sound-letter) similarity of a large part of the Ukrainian and Russian lexicons. Results. Thus, online publications, both national and regional, are characterized by a low degree of language competence. In particular, activity in the use of interference tokens and Russian tokens has been demonstrated.
