Nazwiska współcześnie w Polsce używane z ruskim dub- i polskim dąb- // dęb-. Studium porównawcze)

The article includes a linguistic analysis: semantic and formal (morphological and phonetic-graphic) of nearly 330 surnames of Russian origin and more than 370 Polish surnames, which have been formed on the basis of the Ukrainian, Belorussian and Russian root dub- and Polish dąb- // dęb- (“oak”), excerpted from Słownik nazwisk współcześnie w Polsce używanych (“The Dictionary of Surnames Contemporarily Used in Poland”) from the years 1992-1994. The analysis showed qualitative and quantitative similarities and differences between those two anthroponomasticons and their mutual interferences. They are especially visible in the process of Polonization of Russian surnames, set in a broader context of Polish enculturation of Russian residents in historical Poland. Semantic and formal richness of both anthroponymic families with the root dąb (“oak”) confirmed an important position of dąb in Russian languages as well as in Polish, reflecting the meaning of this tree in the economic and cultural life of man.
