Grammar » -qati (affix)

This very common affix is attached to a verb to indicate someone or some people who do something with someone else:

ilinniaq- 
to study
ilinniaqati
classmate
  
iqqaniajaq-to work
iqqaniajaqatico-worker
  
pi + qati = piqati
 friend; companion

-qati is often followed by the verb -gi- meaning to have, which is in turn followed by a double person ending:

Susi ilinniaqatigijara
Susi is my classmate (literally, I have Susi as a classmate).
KatimaqatigijunnaqqinngaCan you meet with me?

-qati- + -gi- can also  be put in the dual or plural to form a word that can stand on its own:

mumiqatigiik two people dancing together
niriqatigiit 
several people eating together.
