What word would you choose to convey uncertainty in a decision?

The word "waver" effectively conveys uncertainty in a decision. When someone is said to waver, it implies that they are hesitating or struggling to choose between options. This indecision often reflects a lack of confidence or a feeling of uncertainty about the best course of action. In contexts where a person might be deliberating or unable to commit to a specific choice, "waver" captures that state of mental fluctuation or doubt.

In contrast, "certainty" suggests a clear and confident state regarding a decision, which directly opposes the theme of uncertainty. "Decisive" indicates a strong, firm decision-making ability, which also does not align with the idea of uncertainty. Lastly, "resolution" typically refers to the firmness of purpose in making a decision or the act of resolving something, thus denoting a clear, determined outcome rather than uncertainty.
