Two-syllable nominals ending with ⟨-i⟩; consonant gradation possible. Also words formed using the suffix -kki.
Partitive ending ⟨-a⟩/⟨-ä⟩ and genitive plural ending ⟨-en⟩. ⟨-i⟩ of stem changes to ⟨-e-⟩ before plural marker ⟨-i-⟩, except in genitive plural, where it is dropped.
Foreign words and loan words ending in a consonant are often declined following this type: the nominative singular has no ⟨-i⟩ ending, but the rest of the declension is as for an ⟨-i⟩ nominal, including the illative singular ⟨-iin⟩.
Basic declension without consonant gradation
ends with ⟨-i⟩ back vowels (contains ⟨a⟩, ⟨o⟩ or ⟨u⟩)
