An amendment is an addition or alteration made to a constitution, law, or other official document. It modifies or adds new provisions to the original document without fully replacing it. In the context of the United States, an amendment refers specifically to changes made to the Constitution. The Preamble to the Constitution is the introductory statement that sets forth the purposes and guiding principles of the document. It is not considered an amendment. The beginning of the Declaration of Independence is a separate document altogether and is not related to amendments.
