Answer:
The Ninth Amendment was part of the Bill of Rights that was added to the Constitution on December 15, 1791. It says that all the rights not listed in the Constitution belong to the people, not the government.
or in other words you could say, the rights of the people are not limited to just the rights listed in the Constitution.
