Epistemic possibility is expressed with a marker different from the main verb expressing 'ability' (kashitaaw) and from the verbal prefixes expressing 'ability' (kakii-).
For example: ahpeetikwee, maashkut, tetbaen
'perhaps, maybe'.
In addition, there is an epistemic evidential particle eetikwee, which could be called 'suppositive', referring to statements for which one has no direct evidence.
