Its word originates from the Latin cum (with) and statuere (establish). It is defined as the fundamental law of a State, established or accepted as a guide for its governance. It is also known as Magna Carta. The Constitution contains the laws or doctrines that establish the form of political organization of a State, and fixes the limits and relationships between its powers (which are generally the Legislative, exercised by the Parliament, Congress or Assembly; the Executive, exercised by the government; and the Judicial, by the judges). In addition, it establishes the rights and duties of citizens and rulers, as well as the organization of the territory in municipalities, provinces and other divisions, such as the autonomous communities (in the case of Spain) or the states (in the case of Venezuela).
The Constitution can be modified in order to improve or update it, the Constitutional Court is usually in charge of deciding which laws are in conformity with the Constitution and which are not, and if it is an important change, the citizens are consulted or to the people through a referendum or constitutional reform, where by means of the vote they express whether they are satisfied or not with the change. This act is carried out in democratic countries, since in countries with dictatorship, its Constitution is imposed by the dictator, who does not consult either Parliament or citizens.
Most of the countries have a written Constitution, while others do not, such as Great Britain, its Constitution is represented in numerous documents and common law (uses and customs).
Similarly, the word constitution has another meaning; it is the way something is composed or the way its forming elements are structured. Example: "T hese rugby players have a strong and robust constitution ."
