AuxNotVInfl: Auxiliaries are verbs, but the inflection of auxiliaries is not identical to that of lexical verbs.

In Northern Mansi, auxiliaries are conjugated the same way as verbs. For instance, the conjugated auxiliary wērmi ‘able’ with the infinitive of the main verb expresses epistemic possibility (1), while the future tense is coded by the infinitive of the main verb + the conjugated form of the pati ‘begin’ auxiliary (2). Some of the auxiliaries, however, cannot take suffixes like ēri ‘have to’ which expresses situational necessity and does not agree with logical subject neither in person, nor in number (3).
