The term 'Be Sovereign' can be broken down into two crossword solutions: RULE and 4 letters. RULE is defined as having the power to govern or make decisions without interference from others. This term is often used in a political context, where a sovereign state is one that has its own government and is not subject to outside authority. The 4 letters refer to the four elements of sovereignty: territory, population, government, and recognition. These elements are necessary for a state to be considered sovereign. Together, the two solutions suggest that a state must have the power to govern itself and the four elements of sovereignty in order to be considered sovereign.
