Cernelian/Sound changes

Proto-Finnic to Proto-Balto-Slavic parallel (early Proto-Cernelian)

• Secondary stress becomes the primary stress, and the old stress lost

Proto-Finnic *ármastàdak → Early Proto-Cernelian *armastā́ˀ → Late Proto-Cernelian *romostà → Modern Cernelian romosta "to love"

The secondary stress is expected from non-final odd-numbered syllables

• *h-, *-h, and *-k become early Proto-Cernelian glottalized acute -ˀ (final *-h caused lengthening of the preceding vowel)

*habukka → *áuˀka → *ùko → uko "hawk"

*hameh → *áˀmē → *ámě → amie "shirt"

• Intervocalic *-b-, *-d-, and *-g- were lost except before front vowels

*jalaga → *jálā → *jěla → jała "elm"

*jabat → *jā → *jě → je "oars"

• Proto-Finnic *c → *s

*ükci → *iˀsi → *jь̀sь → iś "one"
