. The authoress describes the vocabulary of foreign origin in contemporary Lithuanian dialect of Punsk surroundings (the Punsk commune, Podlaskie voivodeship, in the North-East of Poland). She analyses changes in the use of borrowings in period indicated by the last 3-4 generations. She particularly pays attention to the latest lexical borrowings. The authoress indicated political, economic, social causes which led to the increase in the number of borrowings in the dialect. Moreover she completes the list of old slavisms which have not been mentioned so far. She also specifies the meanings of previously given slavisms. The authoress provides unregistered in the literature of subject singular forms of lexemes previously qualified as pluralia tantum, e.g. 'skripka' (violin) against 'skripkos' (plural); 'vailokas' (felt shoe) against 'vailokai' (plural). A numerous, unsteady group of the most recent polonisms which, as a rule, are quickly replaced by their Lithuanian equivalents under the influence of school was omitted in the list of lexemes of Slavonic origin.
