Ways Greek island gets broadcast (5)
I believe the answer is:
roads
'ways' is the definition.
(I know this)
'greek island gets broadcast' is the wordplay.
'greek island' becomes 'rhodes' (Rhodes is a Greek island).
'gets broadcast' indicates a 'sounds like' (homophone) clue.
'rhodes' is a homophone of 'ROADS'.
(Other definitions for roads that I've seen before include "Routes for vehicles" , "Surfaced ways" , "an answer to all clues, initially" , "Ways, routes" , "Tracks" .)
