When I think of sovereignty I think of power or domination. For example, living in a land where one person (such as a king or ruler) has power of all his people. Sovereignty has an essential meaning, supreme authority within a ground. Per the article the heritage foundation, the United States is in fact a sovereign nation. Which means that the United States is a self-govern nation, administrated by the American people, that controls their individual affairs. When the Americans adopted the Constitution, it was then when the government was formed. As a government, they then elect their own representatives and make their own laws.
In my interpretation, sovereignty has nothing to do with government, as such, sovereignty is the right, or authority,
