Unbothered means staying calm and unaffected when something annoying, stressful, or upsetting happens around you. When you're unbothered, you don't let other people's negativity, drama, or problems disturb your peace of mind.

Picture a student who remains focused on their homework while their siblings argue loudly in the next room. Or imagine someone who keeps walking confidently when others whisper behind their back. That's being unbothered: you notice what's happening, but you don't let it ruin your mood or distract you from what matters.

The word suggests a kind of emotional strength and self-control. It doesn't mean you're cold or that you don't care about anything. Rather, it means you've decided which things deserve your attention and which don't. When your friend teases you about your favorite book and you just shrug and smile, you're unbothered. When someone tries to start an argument but you stay relaxed and friendly, you're unbothered.
