A charter is an official document that grants specific rights, powers, or privileges to a person, group, or organization. When a government issues a charter to a company, it's giving that company legal permission to exist and do business. When a school receives a charter, it gains the authority to operate independently while still following certain rules.

The word comes from medieval times when kings and rulers would write charters on parchment, granting land or special rights to nobles, towns, or trading companies. The Magna Carta, signed in 1215, was a famous charter that limited the power of English kings and established important legal rights.

Today, charter schools are public schools that operate under their own charters, giving them more freedom to try different teaching methods than traditional public schools. A charter member is someone who helped found an organization and was there from the very beginning. When someone charters a bus or boat, they're renting the entire vehicle for their exclusive use, like chartering a yacht for a special trip.

The United Nations Charter, signed in 1945, established the rules and purposes of the United Nations. Similarly, many cities operate under charters that work like constitutions, laying out how the local government functions.
