/ˈsɒvrɪn/ – Noun
Definition: vua, quốc vương, tối thượng, có chủ quyền, có quyền lực.
A more thorough explanation: In legal terms, “sovereign” refers to a government or state that possesses full and independent authority over a geographic area and its inhabitants, without being subject to the control of any other external authority. A sovereign entity has the power to make and enforce laws, levy taxes, conduct foreign relations, and engage in other activities that are characteristic of a self-governing political entity.
Example: The sovereign of the country has the authority to sign treaties on behalf of the nation.
