Ratification is the formal act of officially approving and accepting something, usually a treaty, law, or agreement. When something is ratified, it moves from being just a proposal to becoming binding and real.

The word appears frequently in history and government. After the Constitutional Convention wrote the U.S. Constitution in 1787, it needed ratification by at least nine states before it could become the law of the land. State conventions debated fiercely, and when enough states finally ratified it, the Constitution took effect. Similarly, when countries negotiate a treaty, their governments must ratify it, often requiring approval from a legislature or parliament, before the treaty becomes official.

The process of ratification matters because it provides a check on power. When the Senate ratifies a treaty, it helps ensure that the American people, through their elected representatives, have agreed to the terms. Without ratification, even the most carefully written agreement remains just words on paper.

You'll also hear the word in simpler contexts: a club might ratify new bylaws, or a student council might ratify a decision made by a planning committee. In each case, ratification transforms a proposal into something official that everyone must follow.
