Dubitative mood (abbreviated DUB) 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:

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.
