Permit lady to enrage? Not new (7)
I believe the answer is:
license
'permit' is the definition.
(I know that permit can be written as license)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for license that I've seen before include "Authorise (something)" , "Allow" , "Give permission" , "Entitle" , "Grant official permit to sell or trade" .)
