What does unconceivably mean?
Unconceivably is an adverb meaning “to an extent that cannot be imagined or believed.” It is used to emphasize qualities that seem extraordinarily large, difficult, strange, intense, or otherwise beyond ordinary comprehension. The phrase “an unconceivably difficult problem,” for example, indicates that the problem exceeds what the speaker considers easy to imagine or solve. Unconceivably is closely related in meaning to inconceivably, unimaginably, and unbelievably, but it often carries a more formal, literary tone than everyday alternatives such as incredibly. Its unusual un- spelling is recognized in English, although the more common form is inconceivably. The word is especially effective when the writer wants to convey that reality has exceeded the limits of ordinary visualization or belief. It is consequently more suited to descriptive prose, journalism, literary analysis, and formal commentary than to casual conversation.
