Proto-Nivkh *-nt.

- (North Sakhalin, East Sakhalin) indicative mood marker for verbs
- (South Sakhalin) infinitive marker for verbs (see usage notes)
- (North Sakhalin, East Sakhalin, South Sakhalin) nominaliser (see usage notes)
In South Sakhalin Nivkh, a distinction is made between this suffix, used for the infinitive, and with two other suffixes derived from the same Proto-Nivkh suffix:
As a nominaliser, forms action and result nouns, denotes the instrument or object of an action, or denotes something characterised by the attribute described by the verb (e.g. "to be green" > "verdure").
