repentant
Feeling truly sorry for doing wrong and wanting to do better.
Repentant means feeling genuine sorrow and regret for something wrong you've done, and being determined to do better. When you're repentant, you don't just feel bad about getting caught: you truly wish you hadn't done it in the first place.
A repentant student who copied homework doesn't just mumble “sorry” to avoid trouble. Instead, they feel real remorse, admit what they did, and work to earn back their teacher's trust through honest effort. A repentant friend who spread a mean rumor understands the hurt they caused and takes real steps to make things right.
The word comes from the idea of repenting, which means changing your heart and direction after recognizing a mistake. Someone who is repentant doesn't make excuses or blame others. They face what they did, accept responsibility, and commit to making better choices.
You can see the difference between someone who's truly repentant and someone who just wants to escape consequences. A repentant person's apology feels sincere because it is: they've thought about the harm they caused, they feel genuine regret, and they're already working on becoming someone who won't make that mistake again.
