One of the Balearics (7)
I believe the answer is:
minorca
'one of the balearics' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for minorca that I've seen before include "Balearic island (Eng. sp.)" , "Land in Balearics" , "holiday island" , "Mediterranean island" , "Balearic island; O, cram in (anag.)" .)
