magnanimous
Very generous and forgiving, especially toward someone who wronged you.
Magnanimous means generous and forgiving, especially toward someone you've defeated or someone who has wronged you. A magnanimous person rises above pettiness and treats others with unexpected kindness, even when they have every right to gloat or seek revenge.
Imagine winning a close spelling bee against your biggest rival. A magnanimous winner would congratulate them on their performance and acknowledge how hard the competition was, rather than bragging or rubbing it in. When a team loses a championship game, a magnanimous coach from the winning side might praise their opponents' skill and sportsmanship rather than just celebrating the victory.
Being magnanimous requires inner strength because it means putting aside your ego and treating others with dignity, even when you're in a position of power or advantage. Julius Caesar was known for his magnanimous treatment of defeated enemies, often pardoning them instead of punishing them.
You might hear someone say “that was magnanimous of her” when a person shows unexpected grace or forgiveness. The opposite would be being petty, vindictive, or small-minded. Magnanimity reveals character: anyone can be kind when it's easy, but being magnanimous when you've been hurt or when you've won takes real nobility.
