Plural number is marked in finite verbs in various ways, depending on the arguments whose plurality is being indexed. One set of plural forms are 'primary', that is, once again they refer to either the 'intransitive subject' or the 'transitive object' (the absolutive case agreement). The form of primary plural marking varies irregularly according to the verb stem, and may involve miscellaneous stem changes or the placement of a plural marker immediately adjacent to the singular stem ("-z", "-zki", "-tza", "it-", "-te"). Singular and plural forms of some finite verb stems are shown in the following table.
