Abstract: The purpose of our research is to study the category of emotivity in the Russian popular science text. The main research methods in this case are descriptive method, content analysis and emotive analysis. The linguistic category of emotivity is the subject of the study, and the popular science video "The Russian Language in 18 minutes" is the object. Special attention is paid to the function of the category of emotivity in a popular science text related to the popularization of scientific knowledge. In our work, we have shown that popular science text involves not only emotion-neutral components, but also emotive components, which include, for example, emotive-potentiative, rhetorical question, emojis and emoticons. It is also proved that with the help of emotive components, rigorous scientific information turns into accessible even for non-specialists. The novelty of the research lies in the analysis of the representation of the category of emotivity in a strict scientific style. As a result, it is proved that the category of emotivity can systematically manifest itself in a scientific style as a means of popularizing scientific knowledge, in particular in a popular scientific text. Russian in 18 Minutes, the material we have chosen, can be used as a good example in the class of Russian as a foreign language, the results of our research can also be used in the course of stylistics.
