This article is based on texts recorded during field studies carried out in Daugavpils in the summer of 2019. It compares the language of two representatives of older-generation intelligentsia and juxtaposes the findings with materials from an unpublished doctoral thesis by Malgorzata Ostrówka "Wspólczesna polszczyzna mówiona na Lotwie" ("Contemporary Spoken Polish Language in Latvia"). The author collected her material in the 1990s. In this article we describe both the contemporary and past sociolinguistic situation highlighting changes that occurred in the Polish language.
