Usage notes
This suffix causes syllable reduction and can trigger changes of in the stem to  via the usual vowel harmony. It takes the form after stems that end in  and  when followed by the plural suffix  or the attributivizer.

Verbs converted with this suffix can take series II person markers referring to the argument of an intransitive verb or the patient argument of a transitive verb. Intransitive verbs must also bear the intransitive prefix. However, person marking is optional for them; this is the only type of deverbal nominalization where person marking is optional.

One of the two attributivizers and  can follow this suffix in order to make the word function as a predicate in a subordinate clause of purpose with the meaning ‘in order to X’, ‘for X-ing’. The difference in meaning when used with one attributivizer versus the other is unclear.
