Verb-sentences, or single-word sentences consisting of a stem verb modified by inflectional, derivational and/or other types of affixes, commonly appear in Kaska.

[9] The -d- classifier serves a more complex function, accompanying self-benefactives, reflexives, reciprocals, iteratives (marked by the prefix ne-) and passives.

The conjunct, which appears between the disjunct prefix group and the verb theme, carries inflectional information including subject, direct object and mood/aspect markings.

Postpositional morphemes, such as ts'i'- ("to") and yé- ("about"), also appear in the disjunct, along with the oblique object markings listed in the table below.

Source:[9] In Kaska, time is expressed primarily through aspect marking, called modes when described in Athabaskan languages.

Overt expressions for quantified units of time exist, such as tādet'ē dzenḗs ("three days"), but rarely appear in Kaska dialog.

The perfective mode (prefix n-) functions largely in complement to the imperfective, expressing complete action, is used in descriptions of kinetic events and establishing realis mood.
