- One sound change later, German, Polish, old Swedish etc. use it for /v/, the voiced labiodental fricative.
- Thanks to its vocalic origin, values such as [u] still occur in Welsh.
- w also naturally lends itself to be used as a labialization diacritic.
- Actually, this isn't really "except worse". Values such as /ə/ in Tyl Sjok are definitely farther off than anything I can think of here. Dang.
