Northern Mansi distinguishes between epistemic and situational necessity. Epistemic necessity is expressed by the wos ‘let’ particle and the finite form of the verb (1), while situational necessity is marked by the construction of the infinitive of the main verb + the ēri ‘must’ auxiliary which also requires a dative subject (2).
