The author presents an evolution of her research on Polish linguistic politeness, which in the beginning were held as part of grants related to cultural linguistics. The result were important books: Polish Linguistic Politeness (1977), Dictionary of Linguistic Savoir-Vivre (2014), How the Europeans Address Themselves (2019). The evolution of research developed towards intercultural comparison, the results of which were published in Our and Foreign Politeness (2005) and Politeness at the Ends of the World (2007). An expert on politeness writes that the young generation — in contrary to popular belief — is interested in language etiquette, which is verified by the academic and popular lectures held by the author.
