Surround inhabitants of tropical, man-made island (2,5)
I believe the answer is:
la palma
'island' is the definition.
(Canary island)
'surround inhabitants of tropical man-made' is the wordplay.
I cannot really see how this works, but
'man' could be 'palm' and 'palm' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for la palma that I've seen before include "one of the Canary Islands" , "A Canary Island" , "Spanish island" , "Island of the Canaries" .)
