The term "chief state" refers to the primary governing body of a territory or country. It is a term that carries connotations of leadership and authority. However, there are several antonyms for the term that convey the opposite meaning. One antonym is "subordinate state," which refers to a territory or entity that is under the rule or control of a larger, more dominant state. Another antonym is "minor state," which implies a smaller or less significant governing body in comparison to others. Finally, "dependent state" is an antonym that suggests a state that relies heavily on another for its governance or sustenance. Altogether, these antonyms provide a more nuanced understanding of the complex relationships that exist between governing bodies.
