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 only remnant of e-stem here is the nominative (incl. accusative and vocative) plurals.
There is slight irregularity in the singular ablative form, e.g. **tućsto is simplified to tucto. Before the ending, the sequences **-ćs-, **-dźs- are simplified to -c-, while **-śćs- and **-źdźs- are simplified to -js-. Alongside those, sequences **-czs-, **-szs- and **-żs- are also simplified to -c- (the first one) and -s- (the last two) as well.
