Rearrange a garden in the West Indies (7)
I believe the answer is:
grenada
'in the west indies' is the definition.
('Grenada' is part of 'west indies')
'rearrange a garden' is the wordplay.
'rearrange' indicates an anagram (I've seen this in other clues).
'a'+'garden'='agarden'
'agarden' with letters rearranged gives 'GRENADA'.
(Other definitions for grenada that I've seen before include "Island N. of Trinidad" , "A garden (anag) - Caribbean island" , "Commonwealth country" , "commonwealth state" , "West Indian island" .)
