As in the first part I (Warsaw 2018) the main research goal of the authors is distinguishing East Slavic borrowings from Polish archaisms. These units could be explained as a parallel, convergence, or Polish and Ruthenian neologisms in the Polish language area as a consequence of interference. The detailed and comprehensive analysis considering geographic, chronological and etymological aspects of the selected lexical items, allowed the authors to establish the provenance of the researched vocabulary in a precise and reliable way. The paper is exemplary both in terms of content and applied methodology.
