Entrance to ferry (9)
I believe the answer is:
transport
This clue is a double definition.
'entrance' is the first definition.
(thesaurus)
'ferry' is the second definition.
(thesaurus)
'to' is the link.
(Other definitions for transport that I've seen before include "Entrance" , "Send (convict) to a penal colony" , "Move (from place to place)" , "Move something or someone over a distance" , "Delight; e.g. bus" .)
