One word synonym for "without permission" [closed]

What's a one word synonym for "without permission" when pertaining to one of these (or very similar):

• admittance or entrance

• hunting, fishing, swimming

• shirt, shoes, dogs etc

• eating, drinking

Solution 1:

unauthorised/unauthorized

not having official permission or approval.

• unauthorized access to the computer system (OxfordL)

Or

without someone's official permission to do something or be in a particular place:

• Unauthorized personnel are not admitted beyond this point. (Cambridge)

However, your category of *shirt, shoes, dogs is a bit strange. I don't see how you could say unauthorised shirt, shoes or dogs... Maybe unwanted would go better, but this is a different meaning.

It seems to me that without permission can describe actions, but not persons or objects.

Solution 2:

Unsanctioned is high register but semantically correct.

unsanctioned [adjective]: lacking effective or authoritative approval or consent: not sanctioned ...
