Island where Napoleon was exiled (4)
I believe the answer is:
elba
'island where napoleon was exiled' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for elba that I've seen before include "Napoleon exile island" , "Napoleon's Mediterranean exile island" , "Island of Napoleon's first exile" , "Napoleon's plaint: 'Able was I ere I saw . . . .'" , "Italian isle" .)
