Two-syllable nouns ending with ⟨-a⟩/⟨-ä⟩ not covered by type 9 (kala): those ending with ⟨-ä⟩, or with first vowel ⟨o⟩/⟨u⟩. Also words formed using the deverbal suffix -ja/-jä, adjectives and participles (-(tta)va/-(ttä)vä, -ma/-mä), the numerals seitsemän, kahdeksan and yhdeksän and words derived from them.
Consonant gradation possible.
⟨-a-⟩/⟨-ä-⟩ of stem is dropped before plural marker ⟨-i-⟩. Partitive ending ⟨-a⟩ and genitive plural ending ⟨-en⟩.
The words in the NSK ⟨seitsemän⟩ type have an additional final ⟨n⟩ in the nominative singular, but otherwise their inflection is identical to the koira type.
