Connection out of Dover or Ostend (2-2)
I believe the answer is:
ro-ro
'connection out' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'of dover or ostend' is the wordplay.
'of' indicates a hidden word.
'RO-RO' is hidden within 'dover or ostend'.
Can you help me to learn more?
(Other definitions for ro-ro that I've seen before include "Transport for vehicles with drivers" , "Class of ferry/cargo ship" , "Type of ferry transport for vehicles" , "Kind of ferry" .)
