This paper is the first attempt to compare Czech and Ukrainian communication patterns by means of questionnaires, interviews, introspection and participant observation. The two Slavic nations’ linguistic etiquette is studied in conjunction with their underlying cultural patterns, related to the dimensions of collectivism, individualism, universalism, and particularism. In the focus of the research lie numerous cross-language commonalities, as well as ethnocultural peculiarities of verbal and non-verbal routine formulas.
