What term describes the act of wavering or swaying indecisively?

The term that describes the act of wavering or swaying indecisively is "vacillate." This word encapsulates the concept of fluctuating between different opinions or courses of action, suggesting a lack of firmness in making a decision. It conveys a sense of uncertainty, where an individual may find themselves oscillating between choices or viewpoints rather than committing to one. This behavior can occur in various contexts, such as making personal decisions, professional judgments, or responding to conflicting emotions.

The other terms do not align with the concept of indecision. For instance, "usable" refers to something that is functional or practical, while "vilify" means to speak ill or to defame someone, which involves making a strong stance against a person rather than indecisiveness. "Xerography" pertains to a photocopying process and has no relation to decision-making or wavering. Therefore, "vacillate" stands out as the correct choice by accurately depicting the state of indecisiveness.
