This is a great question because there is so much confusion around both these terms.
Much of the confusion stems from the fact that although both of these terms have a narrow, technically-correct meaning they have also been commonly used to refer to other aspects of self-defense law beyond these core meanings.
In addition, of course, Stand-Your-Ground has been deliberately mischaracterized throughout the media by political activists for their own purposes.
