The nature of a constitution is that it is a set of fundamental principles or established precedents according to which a state or other organization is governed. It outlines the structure, powers, and duties of government institutions, as well as the rights and responsibilities of citizens. A constitution serves as the supreme law of the land and provides a framework for the organization and operation of a government. It is typically written and codified, although some countries have unwritten constitutions based on tradition and precedent. Constitutions can be amended or revised through established procedures to adapt to changing circumstances and societal needs.
