This article examines memes related to the Ukrainian language as universal information units in the online environment, as well as the special role of the Ukrainian language in the creation and functioning of virtual memes. The concept of the meme is defined and specified as an integral and coherent unit of Internet communication that has a standardized form and such characteristics as virality, replicability, emotionality, seriality, mimicry, minimalism of form, multimodality, relevance, humor, mediatization, and creativity. It is noted that most people understand a meme in a narrow sense—as an image, video, fragment of text, etc., which spreads rapidly from one Internet user to another, often with small modifications that make it humorous and highly popular. The article analyzes the patterns of emergence of Internet memes, the reasons for their popularity, and the peculiarities of their functioning online. It examines memes about the Ukrainian language related to the adoption of the 2019 orthographic reform; memes that vividly reflect lexical usage; as well as those connected to the observance of linguistic norms at the levels of morphology, syntax, punctuation, accentuation, and orthography. Contemporary modes of online communication have contributed to the significant spread of such memes on social networks such as Telegram and Facebook, and across the broader Google search environment. Ukrainian-language Internet memes are characterized as emotionally charged units of linguistic information whose source lies in multilevel elements of knowledge of the Ukrainian language. These memes are replicated and disseminated by Internet users in the form of text (inscriptions, captions) (textual), images or videos (visual), or a combination of text and iconic elements (drawings, photos, tables) (creolized or verbal-visual) in the process of communication. The Internet environment today is not only a sphere for the creation and consumption of informational products but also a space for satisfying the informational needs of the modern linguistic individual and for forming certain life orientations and values. Memes, as elements of online communication, harmonize perfectly with the individual needs of speakers and are flexible and adaptive.
