Did you know?

Constitution was constituted in 14th-century English as a word indicating an established law or custom. It is from Latin constitutus, the past participle of constituere, meaning "to set up," which is based on an agreement of the prefix com- ("with, together, jointly") with the verb statuere ("to set or place"). Statuere is the root of statute, which, like constitution, has a legal background; it refers to a set law, rule, or regulation. Constitution is also the name for a system of laws and principles by which a country, state, or organization is governed or the document written as a record of them. Outside of law, the word is used in reference to the physical health or condition of the body ("a person of hearty constitution") or to the form or structure of something ("the molecular constitution of the chemical").

Note: A constitution was originally simply a law, ordinance, or decree usually made by a king, emperor, or other superior authority. A constitution now usually contains the fundamental law and principles with which all other laws must conform. Unlike the U.S. Constitution, the British Constitution is not set down in a comprehensive document, but is found in a variety of statutes (as the Magna Carta) and in common law. Canada inherited many of the rules and practices that are considered part of the British Constitution, but the Constitution of Canada is also set down in comprehensive documents, such as the Constitution Act, 1982 and the Constitution Act, 1867 (formerly called the British North America Act, 1867).
