The paper is an attempt to compare words of Romani origin in the Czech and Croatian languages on the basis of two contemporary lexicographic sources. The main objective is to confirm the thesis regarding the presence of words with the same Romani etymon in both languages as well as to provide the semantic charactersitics of the analysed lexemes. The paper also presents information about the frequency of the words of Romani provenience in the Czech and Croatian languages that were collected using Internet corpora of both tongues
