Authorisation card is forcing freedom (7,7)
I believe the answer is:
driving licence
'authorisation card' is the definition.
The definition suggests a singular noun which matches the answer.
'forcing freedom' is the wordplay.
'forcing' becomes 'driving' (driving is a kind of forcing).
'freedom' becomes 'licence' (licence is a kind of freedom).
'driving'+'licence'='DRIVING LICENCE'
'is' is the link.
Can you help me to learn more?
(Other definitions for driving licence that I've seen before include "Motorist's permit" , "proof of ID" .)
