Introduction. Along with such important issues of speech culture as mastering the rules of spelling and punctuation, lexicology, it is important to study and use the means of expression depending on the purpose and content of expression, governed by grammatical norms of language, deviations from which are morphological and syntactic levels. Violations of morphological norms indicate insufficient attention of media workers to the culture of professional broadcasting, as well as unprofessional editorial processing of materials presented to readers. The purpose of the article is to describe morphological abnormalities in online media, identify the most typical of them and indicate the main erroneous places within the lexical and grammatical class of nouns, numerals, verbs, adverbs formed from numerals. The source base of the study was journalistic texts of online publications of national and regional significance ("Ukrainian Truth", "Doba"). Results. Analysis of morphological deviations within the lexical and grammatical class of nouns showed violations in its formation. Significant difficulties in the inflection of nouns is the genitive singular of the second declension of the masculine gender, namely the correct choice of the ending a (-я) or -у (-ю). In journalistic texts, these endings are interchangeable. he grammatical design of the dative singular of masculine nouns is normative in the analyzed texts. Although most normative sources indicate that the parallel endings овіi (-івi, -євi) / -у (-ю) can be used to denote them, it is stated that the inflections - ові (-eвi, -євi) should predominate in the names of creatures), and in the names of non-beings mostly use -у (-ю). Improper formation of compound numerals also leads to morphological errors. Within the lexical-grammatical class of verbs, the frequency associated with the formation of the imperative mood with the help of the verb tracing paper from the Russian davay / davayte. A powerful source of language pollution of the analyzed online publications is the use of active verbs not peculiar to the Ukrainian language. Forms of active verbs of the present tense in -uch (-yuch), -ach (-yach) are not typical for the Ukrainian language. Conclusion. Thus, the highest frequency in the media texts of the analyzed online publications at the level of morphology are errors associated with the use of uncharacteristic of the Ukrainian language active verbs of the present tense on -уч (-юч), -aч (-яч), with the formation of nouns.
