A payment for a coral island (5)
I believe the answer is:
atoll
'coral island' is the definition.
(I've seen this before)
'a payment for a' is the wordplay.
'a payment' becomes 'toll' (I am not sure about this - if you are sure you should believe this answer much more).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'toll' after 'a' is 'ATOLL'.
Can you help me to learn more?
(Other definitions for atoll that I've seen before include "Allot (anag.)" , "tropical island" , "Key" , "land threatened by rising sea levels" , "Ring-shaped coral island" .)
