parliamentary system
(pahr-luh-MEN-tree, pahr-luh-MEN-tuh-ree) A system of government in which the power to make and execute laws is held by a parliament. Britain has a parliamentary system of government, one of the oldest in the world. The United States does not; its legislature, the Congress, passes the laws, and a separate part of government, the executive branch, carries them out.
