In Surgut Khanty, morphological causation is very rare, it appeares mostly in the case of intransitive > transitive derivation. Transitivity (and causation as subpart of it) is expressed by the -tә suffix, which can be attached to the stem alone (1b) or it can be put after another derivational suffix (2b). If the causer (subject) and the causee (object) are expressed by nominal arguments, they are in their base forms, which is the nominative for both the subject and the object (2b). In order to differentiate between the different semantic roles, the passive construction can be used where the causer is marked with the locative case ending (2c).
