I discuss the linguistic consequences of the current pandemic, such as the emergence of new words and/or an increase in the frequency of use of some pre-existing words, and issues linked to communication. The paper refers to the Polish, Bulgarian and Czech languages. A frequentative approach is applied. Although the outlined linguistic processes are global in nature, several key aspects differentiate the three chosen languages in terms of frequency (including the occurrence of words and functions of speech). The linguistic data was gathered using online resources, including: The National Corpus of Polish, the Czech National Corpus, the Bulgarian National Corpus, the Polish-Bulgarian-Russian parallel Corpus (co-authored by the author of this paper), popular word browsers (frazeo.pl, slowanaczasie) and digital dictionaries (miejski.pl), journalism and information programs, and some of the most recent academic literature.
