What does authorized mean?
Authorized means having official permission, sanction, or approval from a recognized authority. It describes both people — an authorized driver, an authorized representative — and things, such as an authorized payment, an authorized biography, or an authorized version of a text. The adjective derives from the verb "authorize," which traces back through Old French "autoriser" to the Latin "auctor," meaning originator or promoter, the same root that gives us "author" and "authority." Because it implies a formal source of legitimacy, the word carries a neutral-to-formal register and appears constantly in legal, commercial, and administrative language: signs reading "authorized personnel only" are among its most familiar appearances. Its opposite, "unauthorized," signals access or activity lacking official approval. Writers should note the spelling split between American "-ize" and British "-ise" forms. Precise and unambiguous, "authorized" is indispensable wherever questions of official permission arise.
adjectiveHaving official permission or approval to do something; given or sanctioned by a proper authority.
- (of a person) officially permitted to do something
- (of a thing such as a document, payment, or product) officially approved, endorsed, or issued by an authority
"Only authorized personnel may enter the secure facility."
"She is an authorized signatory on all of the company's bank accounts."
"The biography draws on authorized interviews with the singer's closest collaborators."
The word "authorized" literally carries the idea of an author inside it — in Latin, an auctor was someone who increased or validated something, so the person who authorizes you is, in the oldest sense, the one who makes your action legitimate.

Etymology of authorized
Authorized comes from the verb authorize, which entered English in the late Middle Ages via Old French "autoriser," itself from medieval Latin "autorizare." The ultimate root is the Latin noun "auctor" (originator, promoter, guarantor), which also yields English "author" and "authority." The participial form "authorized" developed as an adjective meaning formally sanctioned, and cognates include French "autoriser" and Italian "autorizzare." American spelling retains the -z of the medieval Latin form, while much British usage adopted -s under French influence.
