Being expressed in a consecutive order regular verbal derivatemes in the Abkhaz literary language form a certain kind of hierarchy. In the paper the derivatemes which can change the actant structure of dynamic verbs are considered. The derivateme of noncontrolled action is presented on the highest level of the hierarchy. Next to it comes reciprocal in ajba-, then causative and reflexive, which are followed by reciprocal in aj-. Applicative takes the lowest level. Refactive and associative do not change the actant structure of verbs and so they are out of the hierarhy.

On the basis of the consecutive order of derivatemes an algorithm is worked out. By means of the formal criteria the algorithm determines transitiveness / intransitiveness of verb-forms containing more than one derivational marker.
