Free towns around national park (3,6)
I believe the answer is:
new forest
'national park' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?
'free towns around' is the wordplay.
'around' indicates an anagram.
'free'+'towns'='freetowns'
'freetowns' with letters rearranged gives 'NEW FOREST'.
Can you help me to learn more?
(Other definitions for new forest that I've seen before include "Hampshire woodland" , "rural area" , "Wooded area of Hampshire" , "part of Hampshire" , "area of countryside?" .)
