—sup·pos′er noun Synonyms: conjecture, deem, guess, imagine, surmise, think. To suppose is temporarily to assume a thing as true, either with the expectation of finding it so or for the purpose of ascertaining what would follow if it were so. To conjecture is to put together the nearest available materials for a provisional opinion, always with some expectation of finding the facts to be as conjectured. To imagine is to form a mental image of something as existing, while its actual existence may be unknown, or even impossible. To think, in this application, is to hold as the result of thought what is admitted not to be matter of exact or certain knowledge; as, I do not know, but I think this to be the fact: a more conclusive statement than would be made by the use of conjecture or suppose.
