    Why should I add "d" after the word of authorise?

    Hi all, can you all explain to me why I should add "d" after the word of authorise?

    The photo machine can only be used by authorised personnel.

    I know I should add a "d" after the word of authorise, but why?

    Thanks.

    ...can only be used by an authorised personnel.

    The machine can only be used by someone who is given the authority (authorised)/permission.

    It is the past participle of 'authorise' used as an adjective.

    I would not use "an authorized personnel".

    "... by authorised personnel".
    "... by an authorised person/member of staff".
    Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
