Fighter that's seen on the edge of town (5,4)
I believe the answer is:
green belt
'fighter' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's an association between them I don't understand?
'seen on the edge of town' is the wordplay.
I cannot quite see how this works, but
'on' could be 're' ('on' can be mean 'with reference to') and 're' is found within the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'that's' is the link.
Can you help me to learn more?
(Other definitions for green belt that I've seen before include "Area of open land around a town where building is restricted" , "Undeveloped land surrounding a city" , "Zone where development is banned (in theory)" , "land embracing a community?" , "of restricted development?" .)
