1. To represent to one's self, or state to another, not as true or real, but as if so, and with a view to some consequence or application which the reality would involve or admit of; to imagine or admit to exist, for the sake of argument or illustration; to assume to be true; as, let us suppose the earth to be the center of the system, what would be the result? Suppose they take offence without a cause. (Shak) When we have as great assurance that a thing is, as we could possibly, supposing it were, we ought not to make any doubt of its existence. (Tillotson)
2. To imagine; to believe; to receive as true. How easy is a bush supposed a bear! (Shak) Let not my lord suppose that they have slain all the young men, the king's sons; for Amnon only is dead. (2 sam. Xiii. 32)
3. To require to exist or to be true; to imply by the laws of thought or of nature; as, purpose supposes foresight. One falsehood always supposes another, and renders all you can say suspected. (female Quixote)
