Island ways, they say (6)
I believe the answer is:
rhodes
'island' is the definition.
(Greek island)
'ways they say' is the wordplay.
'ways' becomes 'roads' (road is a kind of way).
'they say' shows a homophone (sound like).
'roads' sounds like 'RHODES'.
(Other definitions for rhodes that I've seen before include "Shored (anag) - Greek island" , "Island, explorer" , "Cycled round hot Society Island" , "See 21 Down" , "British imperialist; Greek island" .)
