Island hotel bankrupted? Not entirely (4)
I believe the answer is:
elba
'island' is the definition.
(I've seen this before)
'hotel bankrupted? not entirely' is the wordplay.
'not entirely' says the answer is hidden in the clue.
'ELBA' can be found hidden inside 'hotel bankrupted'.
(Other definitions for elba that I've seen before include "Able was I ere I saw ... (palindrome)" , "Island of imperial exile" , "Island in the Med" , "Exile isle for Napoleon" , "''Able was I ere I saw . . . .'' (4)" .)
