confront
To face a problem or person directly and deal with it.
To confront means to face something difficult or challenging directly, instead of avoiding it or pretending it doesn't exist. When you confront a problem, you deal with it head-on. When you confront a person, you speak to them directly about something that's bothering you or that needs to be addressed.
Imagine discovering that a friend has been spreading rumors about you. You could ignore it and hope it goes away, or you could confront your friend by calmly asking them about it face-to-face. That takes courage, but it's often the only way to resolve the situation.
The word can apply to all kinds of challenges. A scientist might confront a puzzling question that nobody has solved. A hiker might be confronted by a steep cliff that blocks the trail. In history class, you might learn how different leaders confronted difficult decisions during wartime or a crisis.
Confronting something doesn't always mean fighting or arguing. It means acknowledging what's real and dealing with it honestly, even when that feels uncomfortable. Sometimes the hardest part of solving a problem is simply being willing to confront it in the first place, rather than hoping it will somehow disappear on its own.
