shame
A painful feeling that you are bad or did wrong.
Shame is a painful feeling that comes from believing you've done something wrong or that something is wrong with you. It's different from embarrassment, which usually passes quickly. Shame digs deeper and lasts longer.
When you feel shame, you might want to hide or disappear. A student who gets caught breaking the rules on a test might feel genuine shame, beyond just fear of punishment. That heavy, uncomfortable feeling in your chest that makes you wish you could undo what happened: that's shame. Unlike guilt, which focuses on a specific action (“I did something bad”), shame often makes people feel bad about themselves (“I am bad”).
Shame can be a useful feeling when it helps you recognize you've hurt someone or violated your own values. It can motivate you to apologize, make things right, and choose differently next time. But shame becomes destructive when it's excessive or when it's used as a weapon. When adults shame children with harsh words or public humiliation, they're trying to control through pain rather than teaching through understanding.
Some people also use shame as a verb, meaning to make someone feel ashamed deliberately. And when someone is described as shameless, it means they don't feel shame even when they should, like a player who breaks the rules and then brags about it.
