Which term refers to possessing shrewd judgment or insight?

The term that denotes possessing shrewd judgment or insight is "astute." This word is often used to describe someone who has the ability to accurately assess situations or people and turn that assessment into practical advantage. An astute individual is typically perceptive, can understand complex situations effectively, and demonstrates intelligence and discernment in making decisions. This kind of insight is vital in various contexts, including business, politics, and personal relationships, where assessing situations wisely can lead to successful outcomes.

In contrast, the other terms do not carry the same meaning related to judgment or insight. "Avid" refers to having a keen interest or enthusiasm. "Auxiliary" pertains to providing supplementary or additional support. "Audacious" describes someone bold or daring, often disregarding conventions or norms. None of these words imply the shrewdness or insightfulness that "astute" embodies.
