What does authorization mean?
Authorization is the formal act of granting someone permission to do something, or the permission itself once granted. It sits at the heart of law, business, and technology: a credit card transaction requires the bank's authorization, classified documents require clearance from an authorized official, and computer systems check each user's authorization before allowing access to sensitive data. The word carries an official, institutional tone — it implies not merely casual consent but sanction from a body with genuine power to permit or refuse. It derives ultimately from the Latin 'auctoritas', meaning authority or weight of judgment, making it a close cousin of words like 'author' and 'authoritative'. In everyday use it often appears in set phrases such as 'prior authorization' and 'written authorization', where proof of permission matters. Its counterpart in digital security, authentication, answers the separate question of identity rather than entitlement — a distinction that makes authorization especially useful in precise contexts.

Etymology of authorization
Authorization comes from the verb 'authorize', which entered English in the late Middle Ages via Old French 'autoriser', itself rooted in Latin 'auctoritas' (authority) and 'auctor' (originator, author). The noun form developed as the standard way to express both the act of granting permission and the permission granted. Cognates across Romance languages include French 'autorisation' and Spanish 'autorización'.
