When it comes to bending to someone's will or surrendering to their demands, the phrase "caving in to" is often used. However, there are several synonyms that can be used to convey the same meaning. For instance, you can use "yielding to," "succumbing to," "giving in to," or "bowing to" instead of "caving in to." All these phrases suggest a certain amount of submission or surrender to someone else's desires or demands. Depending on the context, one phrase may be more suitable than the others, but they all convey the same idea of giving up one's own position or beliefs to accommodate someone else's wishes.
