What does veto mean in the context of legislation?

In the context of legislation, veto refers to the right to reject a piece of legislation. This authority is typically held by a head of state or a legislative leader who can prevent the bill from becoming law, even if it has been passed by the legislative body. The veto power is an important aspect of checks and balances within government systems, ensuring that no single entity or individual can have unchecked legislative power. When a veto is exercised, it can also prompt a response from the legislative body, such as an override attempt, which may require a supermajority vote to succeed. This mechanism is designed to encourage dialogue and negotiation between the different branches of government.
