Someone who is brave is willing to do things which are dangerous, and does not show fear in difficult or dangerous situations.

If you brave unpleasant or dangerous conditions, you deliberately expose yourself to them, usually in order to achieve something.

A brave is a young Native American man, especially one who is good at fighting.

If someone is putting on a brave face or is putting a brave face on a difficult situation, they are pretending that they are happy or satisfied when they are not.
