A privilege—etymologically "private law" or law relating to a specific inividual—is a special entitlement or immunity granted by a government or other authority to a restricted group, either by birth or on a conditional basis. A privilege can be revoked in some cases. In modern democracies, a privilege is conditional and granted only after birth. By contrast, a right is an inherent, irrevocable entitlement held by all citizens or all human beings from birth. Miscellaneous privileges, e.g. the old common law privilege to title deeds, may still exist, though of little relevance today.
