Nouns decline for number and case.


Noun roots are inherently transnumeral, that is, whether they are singular or plural must be determined from context. However, suffixes can be applied which make a noun plural, but these are always optional. The most common of these is -Qaa(i)ni, where the Q represents a removal of the rime of the last syllable and where the (i) is only found in rural areas.

  • ex. klito /kʟ̝̊ɪtɜ/ > klitaani /kʟ̝̊ɪtɑːnɪ/ "languages"
  • ex. xokkiij /χɜkːiːS/ > xokkaani /χɜkːɑːnɪ/ "peoples"
  • ex. yijkohaon /jɪSkɜhaɯN/ > yijkohawaani /jɪSkɜhɑːnɪ/
