‘It is allowed to swim in this lake (e.g. because no one is fishing in it)./ One can swim in this lake (e.g. because it is warm enough). (S. D.)

In Northern Mansi, situational possibility can be coded with the following infinitive + auxiliary constructions:

a) Expressing ability:

- infinitive of the main verb + the auxiliary χāsi ‘can/is able’ (1)

b) Expressing permission:

- infinitive of the main verb + the auxiliary wērmi ‘is able’ (2)

- infinitive of the main verb + the auxiliary rōwi ‘is possible’ (3)

c) Expressing the objective possibility of the event:

- infinitive of the main verb + the auxiliary wērmi ‘is able’ (2)

- infinitive of the main verb + the auxiliary rōwi ‘is possible’ (3)

Hence, it can be seen that the constructions containing the auxiliaries wērmi and rōwi can express both permission and circumstantial possibility.
