Anchorage in Greek island, by the sound of it (5)
I believe the answer is:
roads
'anchorage' is the definition.
(roads is a kind of anchorage)
'greek island by the sound of it' is the wordplay.
'greek island' becomes 'rhodes' (I've seen this before).
'by the sound of it' indicates a 'sounds like' (homophone) clue.
'rhodes' sounds like 'ROADS'.
'in' acts as a link.
(Other definitions for roads that I've seen before include "an answer to all clues, initially" , "Area by shore where ships lie at anchor; streets" , "Thoroughfares" , "Surfaced ways" , "Routes for vehicles" .)
