Introduction. The development of society, new historical conditions of existence and social relations lead to the emergence of new words, words and meanings that record new phenomena of social life. The social conditioning of changes is mainly related to the communicative function of language, designed to meet the needs of people in communication, which determines the search for the most rational means of nomination. Methods. To achieve the goal, the method of analysis of linguistic literature and the method of generalization were used. The material of the scientific work was served by lexemes of the concept sphere "pandemic СОVID-19", obtained with the help of a random sample from Ukrainian- and English-language sites and web pages of printed and online mass media. Research results and their discussion. Several linguistic approaches to the study of neologisms that indicate their essence are analyzed: stylistic, psycholinguistic, lexicographic, and denotative. It was determined that linguistics responded to new requests for the language of social practice with dictionaries of a new type for Ukrainian lexicography - neological, or dictionaries of linguistic innovations. We understand neologisms within the scope of our research as structurally, semantically, or stylistically new words that emerged during the COVID-19 pandemic. Extralingual (external) and intralingual (internal) factors contributing to the emergence of new words in the language during the last decades are considered; different approaches to the systematization of neologisms. It has been established that at the current stage, we observe a significant interest in a thorough study of neologisms for the designation of the phenomena of COVID-19, the determination of the linguistic parameters of such innovations, in particular, the methods of their creation, structural and semantic characteristics, which justifies the need for their practical use and study. We consider the research of the outlined layer of vocabulary in the lexicographic aspect to be promising
