Verbal conjugation is agglutinative and verbs may be marked for aspect (imperfective, perfective), valency (transitive, intransitive,
passive, causative), and argument (absolutive, ergative).
The primary division in verbal morphology is made between '''dynamic''' ('''Class I''') verbs and '''stative''' ('''Class II''') verbs. Dynamic verbs denote actions and verbs of motion while stative verbs refer to states of being and include the large class of adjectival verbs, such as ''dreh-'' "to be red", ''mlak-'' "to be dead". A verbal stem belongs primarily to one or other class, depending on its semantics but the boundaries are not inflexible.
| Prefixes || '''Root''' || Derivation || Aspect Marker || Valency Marker || Absolutive || Ergative
The aspect markers are ''-n-'' for the imperfective and ''-k-'' for the perfective in Class I. Class II verbs are not marked for aspect.
The valency markers are ''-a-'' for intransitive verbs, ''-i-'' for antipassive verbs and ''-u-'' for transitive verbs.
The absolutive markers agree with the subject of a intransitive verb or the direct object of an transitive verb. The 3rd person may be animate or inanimate. The 1st and 2nd person forms differ depending on whether they are followed by an ergative marker.
