As it appears on the website: democracy
Democracy is a form of government where the power comes from the people. If people have a direct say, the term direct democracy can be used. However, it is more common to see representative democracies: a democracy in which people vote for representatives, who then in turn make decisions.
A democracy has often something akin to a parliament. This is a legislative, meaning that it makes laws. It serves as a check on the government itself, often having hearings.
