Narrow-minded means unwilling to consider new ideas or different ways of thinking. A narrow-minded person has fixed opinions and refuses to listen when others see things differently. They dismiss possibilities without really thinking about them, like someone who insists there's only one right way to solve a math problem even when classmates show other methods that work just as well.

Imagine a student who loves science fiction but calls fantasy books “stupid” without ever reading one. That's narrow-mindedness: rejecting something based on prejudice rather than experience. Or picture someone who refuses to try foods from other cultures because “they look weird,” missing out on delicious meals their friends enjoy.

The opposite is being open-minded: willing to consider different viewpoints and learn from them. You can disagree with an idea while still thinking about it fairly. A narrow-minded person won't even do that.

The word comes from the idea of a narrow path or tunnel where you can only see straight ahead. A narrow-minded person's thinking feels cramped and limited, like they're wearing blinders. When you stay curious and consider different perspectives, your mind stays open and ready to grow.
