What is primarily modified when amendments are added to the Constitution?

The original text of the Constitution is considered a foundational document that outlines the framework of the government and the rights of the citizens. When amendments are added, they expand upon or clarify the Constitution's provisions without altering the existing text. This means that the original content remains intact while new provisions or rules are introduced through the amendment process.

Moreover, the amendment procedure is designed to ensure that changes can be made in a deliberate and careful manner, thus preserving the integrity of the original document while allowing for adaptability to the evolving needs of the nation. It's a reflection of the balance between maintaining foundational principles and allowing for progress and change.
