When we say someone "is in a quandary," it means they are puzzled or uncertain about what course of action to take. Some possible antonyms for this phrase might include "have clarity" or "are confident." If someone knows exactly what they want to do or how to solve a problem, they are not in a quandary. Alternatively, if they are completely sure of the right choice, they might be described as "resolved." Other opposite phrases could be "are decisive," "are certain," "are determined," or "are resolute." When someone is not in a quandary, it means they have a clear sense of direction and are able to move forward with purpose.
