Usage notesEdit

When the suffix is added to the noun, the stem changes in accordance with consonant gradation. The suffix is added to the plural stem on most hame-type nouns and in many cases of other non-mass concrete nouns, e.g. mainemaineikas instead of **maineekas, kukkakukikas instead of **kukakas.
