Won't change address (4)
I believe the answer is:
town
'address' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Maybe there's a link between them I don't understand?
'won't change' is the wordplay.
'change' is an anagram indicator.
'wont' anagrammed gives 'TOWN'.
Can you help me to learn more?
(Other definitions for town that I've seen before include "Conurbation" , "See 1" , "eg Yeovil" , "What revellers paint red" , "Carmathen?" .)
