The largest of the Balearic Islands (7)
I believe the answer is:
majorca
'the largest of the balearic islands' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for majorca that I've seen before include "Tourist destination" , "Holiday island" , "Palma its capital" , "holiday resort" , "holiday destination ..." .)
