belief held without strong evidence
A belief or idea that something is true, but without good proof or strong facts.
用法パターン：
a supposition that [clause]
よくある間違い：
Learners sometimes use "supposition" in everyday speech where "guess" or "idea" is more natural; "supposition" is quite formal. They may also try to use it as a verb (*"I supposition that…"*), but the verb form is "suppose." Another mistake is using a wrong preposition, such as *"under the supposition that"* instead of the fixed phrase "on the supposition that."
類義語
assumption (More common and slightly less formal; often used for everyday beliefs taken as true without question.)
対義語
fact (A thing that is known to be true and supported by evidence, not just believed.)

unproven idea used for reasoning
An idea that we accept for now, without proof, so that we can think, argue, or do research about it.
用法パターン：
a supposition that [clause]
よくある間違い：
Learners may confuse "supposition" with "proposition." A "supposition" is an unproven starting idea, while a "proposition" is usually a statement or claim that can be argued for or against. Another mistake is using it in very casual speech instead of more natural words like "idea" or "guess."
類義語
hypothesis (Common in academic and scientific contexts; often suggests a more formal, testable idea than "supposition.")
対義語
proven fact (A conclusion that has already been demonstrated or confirmed, not just assumed for the sake of argument or study.)
