Appendix:Finnish declension/sisar

Nominals ending with //; inverse consonant gradation possible.

The inflectional stem is formed by adding to the nominative singular.

Partitive singular ending /, partitive plural ending /, and genitive plural endings and.

Consonant gradation
As endings are attached to the final consonant, the preceding syllable is opened in all cases apart from the nominative and partitive singular (and genitive plural), which may lead to inverse consonant gradation; however this only occurs with → or ∅→.
