Which term refers to a change or addition to the US Constitution?

• A. Amendment
• B. Revision
• C. Addendum
• D. Edit

Answer: (A)

The change or addition to the US Constitution is called an amendment. An amendment is the formal mechanism by which the Constitution is altered, not just tweaked informally. It starts with a proposal—two-thirds of both houses of Congress or a national convention called for by the states—and then must be ratified by three-fourths of the states. This process has produced important updates like the Bill of Rights and subsequent amendments that expand or protect rights and reshape government powers. Other words like revision, addendum, or edit aren’t the official term for constitutional changes: revision suggests a complete rewrite, addendum is a casual note added to a document, and edit is a minor or informal correction, not a formal constitutional change.
