sovereignty
This term carries a heavy weight of legitimacy and absolute control. It is most frequently encountered in political science and international law to describe the legal right of a country to operate without interference from outside powers. It evokes an image of a border that cannot be legally crossed or a law that cannot be overridden by a foreign entity. In a personal or psychological sense, it describes a state of total autonomy over one's own mind and body. This usage is often found in philosophy or self-help contexts, emphasizing the individual's right to make their own choices without being dominated by others or by internal compulsions.
Uncountable when referring to the abstract concept of supreme power. Countable when referring to specific instances or types of autonomous rule, such as the competing sovereignties of various city-states.
