A government is the system by which a state or community is controlled. In the Commonwealth of Nations, the word government is also used more narrowly to refer to the collective group of people that exercises executive authority in a state. This usage is analogous to what is called an "administration" in American English. Furthermore, especially in American English, the concepts of the state and the government may be used synonymously to refer to the person or group of people exercising authority over a politically organised territory. Finally, government is also sometimes used in English as a synonym for governance.
In the case of its broad associative definition, government normally consists of legislators, administrators, and arbitrators. Government is the means by which state policy is enforced, as well as the mechanism for determining the policy of the state. A form of government, or form of state governance, refers to the set of political systems and institutions that make up the organisation of a specific government.
Government of any kind currently affects every human activity in many important ways. For this reason, political scientists generally argue that government should not be studied by itself; but should be studied along with anthropology, economics, environmentalism, history, philosophy, science, and sociology.
