Most people believe the words 'courage' and 'bravery' are interchangeable. That they mean the same thing. However, that is not the case at all.
According to Merriam-Webster, the definition of 'bravery' is as follows.
1 : the quality or state of having or showing mental or moral strength to face danger, fear, or difficulty : the quality or state of being brave
The definition of 'courage' is : mental or moral strength to venture, persevere, and withstand danger, fear, or difficulty
There is a world of difference between facing danger and withstanding it. Particularly when you are the one who must choose to be brave or courageous.
