Disgust is a strong feeling of revulsion or sickened distaste. When something disgusts you, your body and mind react powerfully: you might wrinkle your nose, turn away, or feel like you need to get as far from the thing as possible. The smell of spoiled milk, the sight of moldy food, or touching something slimy and unexpected can trigger disgust.

This intense reaction isn't random. Disgust helps protect us from things that might make us sick, like rotten food or contaminated water. Your brain recognizes potential danger and sends a clear message: stay away from this.

But disgust isn't only about physical threats. People also feel disgusted by behavior they find morally repulsive. You might feel disgusted when you see someone being cruel to an animal or cheating a vulnerable person. When we say someone's actions are disgusting, we're expressing a deep moral rejection, not just distaste.

The word can work as both a verb and a noun. A friend's rude behavior might disgust you, or you might walk away from something in disgust. Notice how the feeling comes with a physical component: true disgust makes you want to create distance, whether from spoiled food or from behavior that violates your values.
