▁are ▁used ▁frequently ▁within ▁the ▁Mat is ▁language ▁to ▁demonstrate ▁the ▁complexity ▁of ▁suffix ation ▁in ▁one ▁of ▁many ▁lingu istic ▁areas . ▁ ▁In ▁Mat is , ▁erg ativity ▁is ▁marked ▁by ▁the ▁morph eme ▁suffix ▁“ - n ” ▁and ▁the ▁absol utive ▁marked ▁with ▁a ▁“ ∅ ”. ▁When ▁there ▁is ▁a ▁final ▁ending ▁of ▁a ▁nom inal ▁root ▁word ▁that ▁ends ▁in ▁a ▁v owel , ▁the ▁erg ative ▁suffix ▁to ▁be ▁applied ▁would ▁be ▁“ - n ”. ▁This ▁is ▁demonstrated ▁in ▁example ▁one . ▁ ▁Example ▁ 1 : ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁ ▁t uma ▁- n ▁aw at ▁- Ø ▁kor oka ▁- e ▁ ▁T uma ▁- erg ▁tap ir ▁- abs . ▁cook ▁- n . pas . ▁ ▁‘ T uma ▁cook s ▁the ▁tap ir ’ ▁ ▁Another ▁suffix ▁morph eme ▁phenomen on ▁with ▁erg ativity ▁is ▁when ▁a ▁root ▁word ▁ends ▁in ▁a ▁nas al ▁sound ▁or ▁“ n ” ▁- ▁or ▁when ▁the ▁root ▁word ▁ends ▁in ▁an ▁al ve olar ▁occ lus ive ▁con son ant ▁such ▁as ▁“ t ”, ▁the ▁initial ▁morph eme ▁“ - n ” ▁all omorph s ▁into ▁“ - an ” ▁which ▁is ▁condition ed ▁by ▁the ▁ending ▁of ▁the ▁root ▁word . ▁This ▁is ▁demonstrated ▁in ▁example ▁two . ▁ ▁Example ▁ 2 : ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁  ▁
