The article was inspired by two recent collective monographs (Divičanová et al., 2015, 2017) dedicated to the surnames used by the families of Slovak origin living in Békéscsaba (Békešská Čaba) and Tótkomlós (Slovenský Komlóš) as the centres of the Slovak ethnic community in south-eastern Hungary whose members started to settle in this part of the historical “Lower Land” as early as in the first quarter of the 18th century. In the above-mentioned publications, hundreds of surnames were analysed from various onomastic aspects (structural types, origin, onymic motivation, etc.). In this study, the author focuses on some questions of etymology and presents alternative explanations for about 30 surnames. In his opinion, some of the surnames under discussion may reflect autochthonous substantial formations otherwise not attested as common nouns in the Slovak language (Hamza, Holok, Lászik, Losjak, Rotyis, Szpluvák); for other surnames, the author identifies possible sources in various foreign languages historically used in this part of Central Europe, i. e., Hungarian (Balán, Csilek, etc.), Romanian (Drimba, Opra, Tirják, etc.), German (Baiczer, Gofjár, Majzik, Matajsz, etc.), Latin (Filadelfi), Polish (Kendra) and Slovene (Raspotnik).
