Island has a charge for road use (5)
I believe the answer is:
atoll
'island' is the definition.
(I know that atoll is a type of island)
'a charge for road use' is the wordplay.
'a charge' becomes 'toll' (toll is a kind of charge).
'for' says to put letters next to each other (I've seen this in other clues).
'road use' becomes 'a' (I can't explain this - if you can you should believe this answer much more).
'toll' put after 'a' is 'ATOLL'.
'has' is the link.
Can you help me to learn more?
(Other definitions for atoll that I've seen before include "tropical paradise?" , "Pacific coral island" , "Land around a lagoon, such as Bikini" , "tropical island" , "Ring of coral" .)
