This paper discusses an issue of the Carpathian lexical group in southern Silesian dialects on the Czech - Polish borderland (gwary cieszynskie). Some vocabulary of this Carpathian group can be partially linked to the history of Walachian settlements that had been established in a broader Carpathian Mountains area during the 16th - 17th century. This article gives a genetic and semantic description of the following words: 'gielata', 'gnot', 'gowiydz', 'grapa', 'grón', 'grudka', 'gunia' and offers an explanation on how or from which areas these words were transmitted into the Silesian dialects (gwary cieszynskie). This analyses proves a consistency in usage of these particular words in the eastern Polish subcarpathian region (Podkarpacie) - generally one word possessed a single phonetic and semantic variant. However, a more differentiated 'lexical situation' can be observed in the southwestern part of this region, including the area the above mentioned dialects were spoken. Especially, semantic changes of the words of 'gielata' and 'gunia' point to an important process: the further to the West, and the bigger the distance from their lexical source was, the narrower became their semantic fields.
