Half of Hispaniola (5)
I believe the answer is:
haiti
'half of hispaniola' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for haiti that I've seen before include "W. Indies republic on Hispaniola" , "Western half of Hispaniola" , "West part of Hispaniola" , "West Indies republic" , "West Indies country, capital Port-au-Prince" .)
