What adjective describes someone who is courageously noble and generous?

The adjective that describes someone who is courageously noble and generous is "magnanimous." This term is derived from Latin roots, where it conveys the idea of having a great spirit. Magnanimous individuals often demonstrate a readiness to take action for the benefit of others, showing both kindness and a willingness to forgive. They are not only noble in their intentions but also generous in their actions, reflecting a high-minded approach to relationships and conflicts.

In contrast, the other options represent traits that are contrary to the idea of magnanimity. For instance, being selfish involves a lack of concern for others, which counters the notion of generosity. Arrogance implies an inflated view of oneself without regard for others, while indifference suggests a lack of caring or concern, entirely missing the noble and generous spirit that defines a magnanimous person. Thus, "magnanimous" stands out as the most fitting descriptor for someone embodying courage, nobility, and generosity.
