Did train around island (8)
I believe the answer is:
trinidad
'island' is the definition.
(I know that Trinidad is a island)
'did train around' is the wordplay.
'around' indicates an anagram.
'did'+'train'='didtrain'
'didtrain' with letters rearranged gives 'TRINIDAD'.
(Other definitions for trinidad that I've seen before include "Port of Spain island" , "West Indies island" , "Caribbean island" , "... [WI ISLAND]" , "Island linked to Tobago" .)
