A charter is the grant of authority or rights, stating that the granter formally recognizes the prerogative of the recipient to exercise the rights specified. It is implicit that the granter retains superiority (or sovereignty), and that the recipient admits a limited (or inferior) status within the relationship, and it is within that sense that charters were historically granted, and it is that sense which is retained in modern usage of the term. The word entered the English language from the Old French , via Latin , and ultimately from Greek (, meaning "layer of papyrus"). It has come to be synonymous with a document that sets out a grant of rights or privileges. Other usages The term is used for a special case (or as an exception) of an institutional charter. A charter school, for example, is one that has different rules, regulations, and statutes from a state school. Charter can be used as a synonym for "hire" or "lease", as in the "charter" of a bus, boat or plane. A charter member (US English) of an organization is an original member; that is, one who became a member when the organization received its charter. A chartered member (British English) is a member who holds an individual chartered designation authorized under that organization's royal charter. Different types of charters Anglo-Saxon charters Anglo-Saxon charters are documents from the early medieval period in Britain which typically make a grant of land or record a privilege. They are usually written on parchment, in Latin but often with sections in the vernacular, describing the bounds of estates, which often correspond closely to modern parish boundaries. The earliest surviving charters were drawn up in the 670s; the oldest surviving charters granted land to the Church, but from the 8th century surviving charters were increasingly used to grant land to lay people. Charter colony The British Empire used three main types of colonies as it sought to expand its territory to distant parts of the earth. These three types were royal colonies, proprietary colonies, and corporate colonies. A charter colony by definition is a "colony chartered to an individual, trading company, etc., by the British crown." Although charter colonies were not the most prevalent of the three types of colonies in the British Empire, they were by no means insignificant.
