Largest of the Balearic Islands (7)
I believe the answer is:
majorca
'largest of the balearic islands' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for majorca that I've seen before include "Mediterranean island" , "Palma its capital" , "Main Balearic island" , "Tourist destination" , "Largest Balearic Island" .)
