Its community spirit all that remains? (5,4)
I believe the answer is:
ghost town
'remains?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'its community spirit all' is the wordplay.
I cannot quite understand how this works, but
'community' could be 'town' (I've seen this before) and 'town' is located in the answer.
'spirit' could be 'ghost' (ghost is a kind of spirit) and 'ghost' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'that' acts as a link.
(Other definitions for ghost town that I've seen before include "abandoned position" , "Empty place" , "There's nobody in it" , "Deserted urban area" , "Deserted community" .)
