In Northern Mansi, if the causal relationship is expressed by a construction which contains two finite verbs and a connective element (1), the verb form does not differ from the one used in simple sentences. In the example, the verb is in the passive voice and thus the second lative suffix is an agent marker. However, the primary way of expressing causal relations in Northern Mansi is to use participle constructions. Participle (2) or gerund (3) constructions contain special verb forms (Sz. Kispál 1966).
