Appendix:Finnish declension/kalleus

Nominals ending with ⟨-(u)us⟩/⟨-(y)ys⟩ — these are mainly nouns formed from nouns and adjectives using the suffix -uus. See also type 39 (vastaus).

Inflectional stem replaces ⟨-s⟩ with ⟨-te-⟩, which is subject to ⟨t⟩ → ⟨d⟩ consonant gradation. Before the plural marker ⟨-i-⟩, ⟨-s⟩ is instead replaced with ⟨-ks-⟩.

Partitive singular ending ⟨-ta⟩/⟨-tä⟩, attached to the inflectional stem without the ⟨-e-⟩, partitive plural ending ⟨-a⟩/⟨-ä⟩ and genitive plural ending ⟨-en⟩.
