Proto-Finnic/Later phonological changes

This is a list of post-Proto-Finnic phonological changes, ordered from the most divergent to the most conservative languages.

Livonian

edit
  • /aː//oː/.
  • Loss of consonant gradation, with single consonants merge to unvoiced consonants (voiced between sonorants, vowels, and word-finally), while long and semi-long consonants merge to unvoiced consonants. *Vettä*vetävietā "some of the water".
  • Palatalization of /s/ and /ts/ after voiced consonants and vowels to /ʃ/ and /tʃ/ before /i/, later phonemized following the loss of /i/.
  • Elisions of unstressed short vowels in an interlocking style:
    • Apocope of word-final /n/, and this must have happened before the next change: *magon*magoma'g "of the belly". This often caused syncretism between nominative and genitive, but some cases do not: nominative ve'ž "water" vs. genitive vied "of the water".
    • Elision of vowels preceding weak grade consonants (/β/, /ð/, /ɣ/, /h/): *kalada*ka'ldõka'llõ. The elided vowel results on the rising tone of the preceding short vowel.
    • Apocope of unstressed vowels other than /ɑ/: *vecive'ž "water", but *jalkajālga "leg" (compare Estonian jalg). The elided vowel also results on the rising tone of the preceding short vowel.
  • Clipping of unstressed long vowels (e.g. *aa), umlauted vowels (e.g. ), and diphthongs (e.g. *ai) to short vowels (a) unumlauted vowels (a), and monophthongs with first components (a), respectively.
  • Lengthening of certain syllables:
    • All closed syllables lengthened their vowel, except when following another closed syllable.
    • Open syllables following another open syllable lengthen their vowels: *kalaka "fish". This was originally an allophonic development, as in Finnish where an open syllable following another open syllables pronounced with a semi-long vowel.

Estonian

edit
  • Elision of vowels in certain circumstances:
    • After a heavy syllable: *suurisuur "big".
  • Apocope of word-final /n/, and this must have happened after the previous change, unlike in Livonian: *suurensuure "of the big one".
