Examples

The most linguistically well-grounded and widely accepted is from the Proto-Balto-Slavic root *mŭzg-/muzg- from the Proto-Indo-European *meu- "wet", (Russian) main citation citation so the name Moskva might signify a river at a wetland or a marsh.
There has been no agreement regarding which archeological formation such hypothetical Proto-Balto-Slavic community would correspond to.
