What term is used to describe a proposed change to the Constitution?

The term used to describe a proposed change to the Constitution is "Amendment." In the context of U.S. constitutional law, an amendment refers specifically to a formal change or addition to the Constitution. The process for amending the Constitution is outlined in Article V, which establishes the procedures for proposing and ratifying amendments. This typically requires either a two-thirds majority in both houses of Congress or a convention called by two-thirds of state legislatures.

While a "bill" generally refers to proposed legislation that may become law but does not specifically alter the Constitution, a "resolution" can pertain to decisions or expressions of opinion by legislative bodies and does not involve constitutional changes. A "statute" is a written law enacted by legislative authority and is not considered a part of the Constitution itself. Thus, "Amendment" is the precise term used for changes to the Constitution, distinguishing it from other legislative processes and types of law.
