Consonant gradation
The long vowel of the inflectional stem means that all cases are in the strong form, other than the nominative and partitive singular. Because of this inverse consonant gradation, it is not always possible to deduce the inflectional stem from the nominative form alone — compare kirves : kirveen and varvas : varpaan.
