Veto

Meaning:

A "veto" is a noun and a verb that denotes the act of rejecting or prohibiting a decision, proposal, legislation, or action. It is an official power or right held by an individual or a governing body to block or prevent the implementation of a particular course of action. When someone exercises a veto, they essentially say "no" to the proposed idea or action, preventing it from becoming effective or going forward. Veto power is often seen in government systems, where a leader, such as a president or governor, can reject bills passed by a legislative body. It serves as a crucial mechanism for checks and balances in decision-making processes and is also used in various organizational and decision-making contexts to ensure that certain criteria or interests are met before proceeding with a plan or action.
