What is the best definition of "arrogance"?

Arrogance is best defined as overconfidence, which captures the essence of the term. It refers to an attitude of superiority displayed through excessive pride or self-importance, often leading individuals to have an inflated sense of their own abilities or worth. This overconfidence can result in a lack of consideration for others, suggesting that an arrogant person may believe they are better than those around them. The focus on self-assurance and entitlement distinguishes arrogance from mere confidence, where the latter is usually balanced with humility and respect for others.

The other options do not align with the meaning of arrogance. Lack of freshness pertains to newness, which is unrelated. Harsh speech refers to a manner of speaking rather than an attitude of self-importance. Ordinary behavior implies a lack of distinction or superiority, which contradicts the very nature of arrogance. Thus, understanding arrogance as overconfidence provides a clear and accurate representation of its definition.
