What is a synonym for "capricious"?

A synonym for "capricious" is "whimsical" because both terms describe behavior or actions that are unpredictable and often determined by impulse rather than consistent reasoning. "Capricious" refers to sudden changes in mood or behavior, while "whimsical" conveys the idea of being fanciful or playful, often showcasing unpredictability. This similarity in the nature of the words makes "whimsical" an appropriate synonym for "capricious."

In contrast, the other options suggest stability or reliability, which is the opposite of the qualities expressed by "capricious." The terms "stable," "consistent," and "predictable" all imply a regularity and dependability that contradicts the erratic essence of being capricious.
