A more thorough explanation:

Definition: Veto means to stop or prevent a decision or action made by someone else. In politics, it usually refers to the power of a leader to reject a law passed by the legislative branch. For example, the President of the United States can veto a bill passed by Congress, which means the bill will not become a law unless Congress can get enough votes to override the veto.

Example: The President vetoed the bill that would have increased taxes on businesses. This means the bill did not become a law, and the taxes did not go up.

Explanation: The example shows how the President used their power of veto to stop a bill from becoming a law. This prevented the tax increase from happening, but it also meant that Congress would need to get more votes to override the veto if they still wanted the bill to become a law.
