When someone "clouds the issue," they make a situation less clear or harder to understand than it should be. To convey the opposite meaning, we can use various antonyms of the phrase. For instance, we can say someone "clarified the issue" if they made the situation more understandable. Alternatively, we could say they "uncovered the truth" if they revealed the facts that had been obscured. Additionally, we may use antonyms such as "simplified the matter" to suggest that someone made the issue more straightforward or "crystallized the situation" to imply that it has become more precise and clear-cut. Employing these antonyms signifies a desire to promote transparency, precision, and simplicity in communication.
