An amendment is a formal change or addition made to a law or document. In the context of the United States, amendments refer to changes made to the U.S. Constitution. These changes can address various issues, such as individual rights or government powers, and are essential for adapting the Constitution to the needs of society over time. The process of creating an amendment involves several steps. First, a proposal must be made, which can be initiated by either Congress or a national convention. Then, the proposed amendment must be ratified by a majority of the states, ensuring that it reflects the will of the people.
