This article presents the essential information about the Polish language variety in Stubno, a village located about 20 km north-east of Przemyśl, close to the border with Ukraine. Until 1945, the village was inhabited by Poles, Ukrainians and Jews. A significant part of the paper is devoted to some passages authored by one M.W,. a woman who lived in Stubno in 1924-2004 and kept records in her personal journals from 1981 and until her death. In this case, her parents were Poles, but maternal grandparents were of Ukrainian descent. The author of the analysed texts received primary education only, worked on a farm and raised children and never left the village for long periods of time. Also, the notes contain a number of information concerning mostly farming and significant events of both the country’s and the world’s history. In addition, the texts include a language commentary on the most important phonetic, morphologic, word-formation, syntactic and lexical features of the local variety that occurred in the records. Furthermore, the notes provide answers to some questions about regional features of the Southern Kresy (present-day Ukraine) as reflected in the language of native inhabitants including the extent of the influence of Ukrainian, together with its local variety of the Nadsannia region.
