Hide port (7)
I believe the answer is:
harbour
I believe this clue is a double definition.
'hide' is the first definition.
(harbouring is a kind of hiding)
'port' is the second definition.
(harbour is a kind of port)
(Other definitions for harbour that I've seen before include "provides shelter" , "Bear" , "Hide - entertain - port" , "Sheltered port" , "Dock" .)
