In our paper we added motivations of some of the oldest names of rivers or creeks. The oldest
hydronyms in the river basin of the Slovak left-sided tributary of Morava are from 13th century.
Most of them are of old Slovak (Slavic) origin, but in addition to local people some such as other
ethnic groups Germans, Hungarians and Croats began to settle there, which it had affected some
toponymics of this region.
