Bikini, for instance, at a high price (5)
I believe the answer is:
atoll
'bikini' is the definition.
(Bikini Atoll is an example)
'at a high price' is the wordplay.
'at' is a charade indicator (letters next to each other).
'high price' becomes 'toll' (I can't justify this - if you can you should believe this answer much more).
'a'+'toll' is 'ATOLL'.
'for instance' acts as a link.
Can you help me to learn more?
(Other definitions for atoll that I've seen before include "Coral island(s) surrounding a lagoon" , "Bikini, say" , "Allot (anag.)" , "Circular coral reef" , "Ring-shaped coral island" .)
