Dubitative mood
Dubitative mood (abbreviated ) is an epistemic grammatical mood found in some languages, that indicates that the statement is dubious, doubtful, or uncertain. It may subsist as a separate morphological category, as in Bulgarian, or else as a category of use of another form, as of the conditional mood of Italian or French: "Il a été amené à l'hôpital" "He was taken to hospital," "Il aurait été amené à l'hôpital" "He was apparently/He is said to have been/We believe he was/The information we have is that he was taken to hospital." An example can be taken  from Ojibwe, an Algonquian language of North America. Verbs in Ojibwe can be marked with a dubitative suffix, indicating that the speaker is doubtful or uncertain about what they are saying. So "aakozi" means "he is sick", while "aakozidog" can be translated as something like "he must be sick; I guess he's sick; maybe he's sick; he might be sick."
