vacillate

To vacillate is to waver between different opinions or actions, unable to make up one's mind. Imagine someone standing at a crossroads, physically turning their head back and forth toward two different paths, unable to commit to either direction. This word is typically used in formal or intellectual contexts to describe indecisiveness regarding important choices. It implies a lack of resolve or a state of fluctuation, often suggesting that the person is going back and forth in a way that is visible or frustrating to others.
