@Blickers,
Quote:To "belie"means you have proved a certain indicator or assumption to be ultimately untrue.
I think that's putting it too strongly. "Belie" has been defined in a variety of ways, but, generally speaking, I don't think it means anything has been "proven." The suggestion is more that something inconsistent or contradictory is being exhibited. To "belie" means something more like "to cast doubt on" than it does "to prove wrong."
To me, a synonym might be "undercut," or "undermine," i.e., cast doubt on it's foundation or validity. But "doubts" are not proofs. They simply raise questions.
Example:
Joe says: Today in Monday.
Jack says: No, today is Tuesday.
What Jack says "belies" what Joe said. They can't both be right, but Jack disagreeing does not prove that he is right.
