Cernelian/3rd declension
Nominals ending in soft -∅. Because in Proto-Finnic this type ends in -i which transparent in vowel harmony (łólcho "in the stupid one" vs. nirsze "in the dull one"), it split into four subtypes. While in other Finnic languages e-stem is more alive, i-stem is much alive here and the e-stem of 3rd declension simply died. The remnants of e-stem here is the nominative (incl. accusative and vocative) plurals, and locational singular cases, as a result of the mixing of i-stems and e-stems (the genitive forms are already similar to each other).
Type 3A
Nominals with stems ending in -b, -ć, -dź, -j, -m, -ń, -p, -ś, -w, and -ź (all letters containing acute accent like -dź always written -Ci(V)- before vowels). It has back vowel harmony.
