Sound changes from Proto-Finnic

  • Initial v becomes p, as in pïḍ "stream" <- virta
  • Medial l becomes alveolar retracted in native vocab, as in kas̠ "fish" <- kala
  • Vowel shifts and umlaut: swïx "kin" <- suku, ïpšn "I studied" <- Estonian õppisin, söwr "society" ~ seura
  • Begadkefat spirantization: t tt -> θ t etc.
