  • consonant stems
  • sk- is added to verb-stems ending in vowels, -isk- to consonant stems. (wikipedia.org)
  • Generally speaking, there are two distinct patterns of strong and weak grades that occur in words: Consonant stems are sometimes said to have "inverse gradation", because the "dictionary forms" of the words exhibit a weak grade and gradate "in reverse" to a strong grade in other forms. (wikipedia.org)
  • By and large, this is still applicable to modern Finnish, this explains the distinction between consonant stems and vowel stems: in consonant stem nominals, the final consonant itself closes the preceding syllable, while in verbs, the combination of stem-final consonant plus the infinitive ending closes the preceding syllable.
