America's road to liberation? (7)
I believe the answer is:
freeway
'america's' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'road to liberation?' is the wordplay.
'road' becomes 'way' (I've seen this in other clues).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'liberation?' becomes 'free' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'way' after 'free' is 'FREEWAY'.
Can you help me to learn more?
(Other definitions for freeway that I've seen before include "No tolls on this major road!" , "road in US" , "Motorway on which stopping or parking is forbidden" , "Road without tolls" , "American road" .)
