authorised

Authorised is the standard British English past tense and past participle of the verb authorize, and also an adjective meaning having been given official approval or permission. In American English the equivalent form is authorized, and the corresponding noun is authorization rather than authorisation.

As a verb form, authorised appears in phrases such as the bank authorised the loan or the contract was authorised by the board. As an adjective, it describes items or persons approved by an authority, for example authorised personnel, an authorised dealer network, or authorised capital in corporate law.

In practice, authorised status denotes formal permission granted by an authority—be that a government body, a company board, or a regulatory agency. Fields that frequently use the term include finance, logistics, aviation, and information security, where access, actions, or entities must be officially approved to operate.

Etymology: authorised comes from Middle English via Old French authoriser, from Latin auctor meaning originator or author. The related noun forms are authorisation (British) or authorization (American), referring to the act, document, or grant of permission that confers authorised status.
