sportsmanship
Fair and respectful behavior when you compete or play games.
Sportsmanship means playing fairly, treating opponents with respect, and handling both victory and defeat gracefully. Good sportsmanship shows up when a soccer player helps an opponent off the ground after a collision, when a chess player congratulates the winner after a tough loss, or when a winning team doesn't gloat or mock the other side.
The word applies beyond organized sports. You show sportsmanship in a classroom spelling bee by rooting for competitors even when you want to win, or in a video game by not exploiting glitches that give you an unfair advantage. Someone with good sportsmanship follows the rules, accepts the referee's calls without constant arguing, and values the competition itself more than winning at any cost.
The opposite is poor sportsmanship: blaming others for your mistakes, making excuses when you lose, celebrating victories by taunting opponents, or bending rules to gain an advantage. A sore loser and a gloating winner both display poor sportsmanship.
Real sportsmanship means understanding that how you compete matters as much as the outcome. You can play intensely, trying your absolute hardest to win, while still respecting your opponents and the game itself. That balance between fierce competition and mutual respect is what sportsmanship is all about.
