Coastal road announced comes to port (6)
I believe the answer is:
beirut
'port' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'coastal road announced' is the wordplay.
I cannot quite understand how this works, but
'road' could be 'rut' (rut is a kind of road) and 'rut' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'comes to' acts as a link.
Can you help me to learn more?
(Other definitions for beirut that I've seen before include "Capital of 21 across" , "Capital city of Lebanon" , "Middle East capital" , "Lebanon's capital" , "Lebanese capital" .)
