Reconstruction:Proto-Slavic/vъz

• *uz

From Proto-Balto-Slavic *uź, cognate with Lithuanian už, Latvian uz. Further etymology is disputed. Derksen tries to derive from a proto-form *ups, but fails to see how it could account for the Baltic facts. Snoj considers relation to Proto-Indo-European *úd(s) (“out”), which otherwise yields Proto-Slavic *vy-. Compare Proto-Germanic *uz.

*vъz[1][2][3]

1. (+accusative) instead of, in return for
2. (+accusative) up, above
3. (+accusative) by, beside

Used also as a prefix *vъz-.

• *za
• *jьz

• *vъz gorě (“beyond the top/zenith”)
• *vъz dolě (“beyond the bottom/nadir”)

• *vysь (“elevation, top”), *vysokъ (“high”) (possibly)
