Sicily, eg (6)
I believe the answer is:
island
'sicily eg' is the definition.
(I know that Sicilia is a island)
This is the entire clue.
(Other definitions for island that I've seen before include "See 1" , "Boffin, Baffin or Barbados" , "Tract surrounded by water" , "Such as Crete, say" , "Lewis and Harris, possibly" .)
