What is an amendment to the constitution And why is the procedure so difficult to accomplish this change?

An amendment to the Constitution is a formal change or addition to the text of the Constitution itself, which requires a rigorous process to ensure stability and reflect broad consensus. This procedure is challenging because it requires either a two-thirds majority in both houses of Congress or a convention called by two-thirds of state legislatures, followed by ratification from three-fourths of the states. This high threshold is designed to prevent hasty or impulsive changes to the foundational legal framework of the government. As a result, amendments are relatively rare and often reflect significant national consensus.
