What is the term for changes to the Constitution?

The correct term for changes to the Constitution is "amendments." This specifically refers to formal modifications or additions made to the Constitution, which must go through a defined legislative process. In the United States, for instance, an amendment requires approval by two-thirds of both houses of Congress followed by ratification from three-fourths of the states.

While other terms like "revisions," "alterations," and "declarations" might imply some form of change, they do not accurately represent the formal process defined in the Constitution. Revisions suggest a more informal or less structured change, whereas alterations and declarations are not terms formally recognized within constitutional law as a method of changing the Constitution. Only amendments carry the legal significance and procedural requirements necessary to modify the foundational legal document.
