Secreted around island (5)
I believe the answer is:
crete
'island' is the definition.
(Greek island)
'secreted around' is the wordplay.
'around' indicates the answer is hidden within the clue.
'CRETE' can be found hidden inside 'secreted'.
(Other definitions for crete that I've seen before include "Mediterranean island with Minoan remains" , "Mediterranean island, capital Heraklion" , "Herakleion its big port" , "Largest Greek island" , "Large island south of Greece, once home to the Minoans" .)
