Usage notes[edit]

  • (multiplicative) Used only with small numbers, and with some pronouns; note that yksi ‎(one) → yhdesti ‎(once) is not standard Finnish (compare kerran).
  • (adverbial suffix) The suffix is appended to the weak stem, i.e. one takes the n off the genitive singular form and adds this suffix to it. The resulting adverb is comparable, if the base word is comparable: for example kauniisti, kauniimmin (more beautifully), kauneimmin (most beautifully). It can be appended to all adjectives, but also to selected nouns and numerals.
  • (intensifier) The suffix is often applied to a vulgar term: perkeleperkeleesti.


  • (expression of how many times something happens): kertaa
