Dual naming
The reasons for the dual naming of the river as Neris by the Lithuanians and Viliya (formerly Velja, meaning "big, great" in Slavic) by the Slavs are complex. Even in Vilnius, there are toponyms including both names, e. g. Neris remains in the riverside names of Paneriai and Paneriškės while Velja is a part of the name Valakampiai, which means "an angle of Velja" in Lithuanian. In Kaunas, a part of the city by the Neris river, that was formerly a separate town, is also named Vilijampolė (Vilija + polis, that means "polis by Vilija").
