All Taba verbs having Actor arguments carry affixes which cross-reference the Number and Person of the Actor, examples of proclitics are shown above. In Taba, there are valence-changing affixes which deal with patterns of cross-referencing with three distinct patterns. The dominant pattern is used with all verbs having an Actor argument. The other two patterns are confined to a small number of verbs: one for the possessive verb, the other for a few verbs of excretion. This is discussed further in Possession below.
