What does “checks and balances” mean?

"Checks and balances" is a principle of democratic governance where power is distributed and separated among different branches of government. Each branch has specific powers and responsibilities, and they each have the ability to limit or “check” the powers of the other branches to ensure that no branch becomes too powerful and abuses its authority. This system is designed to prevent the concentration of power in any one branch of government and to promote accountability and transparency.
