Bikini perhaps missing top shows damage (4)
I believe the answer is:
toll
'damage' is the definition.
The answer and definition can be both related to property as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'bikini perhaps missing top' is the wordplay.
'bikini perhaps' becomes 'atoll' (Bikini Atoll).
'missing top' means to remove the first letter.
'atoll' with its first letter taken away is 'TOLL'.
'shows' acts as a link.
Can you help me to learn more?
(Other definitions for toll that I've seen before include "Tax for using a service" , "Road/bridge charge" , "Sum payable to use main road (4)" , "Ring bell with slow strokes" , "Tax - strike - ring" .)
