What does unknowledgeable mean?
Unknowledgeable is a formal adjective meaning that something is impossible to know or comprehend. It is stronger than merely obscure or unfamiliar: the adjective presents the subject as lying beyond the reach of available knowledge. In sentences about motives, causes, futures, or ultimate questions, it signals an epistemic limit rather than simply the writer's ignorance. The word is much less common than the closely related unknowable, which is also its most natural modern synonym, and it has a distinctly literary or philosophical tone. “Unknowledgeable” should not be used to mean that a particular person lacks information; knowledgeable, with the same root but no negative prefix, describes someone who has knowledge. A clear example is a researcher calling the origin of the universe “fundamentally unknowledgeable.” The word is worth knowing as an exact, slightly archaic alternative to unknowable and a reminder that English can transform a description of someone's expertise into a statement about the limits of knowledge itself.
