A port many get across to (5)
I believe the answer is:
dover
'a port' is the definition.
(English port)
'many get across to' is the wordplay.
I cannot quite see how this works, but
'many' could be 'd' and 'd' is found in the answer.
'across' could be 'over' (synonyms) and 'over' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dover that I've seen before include "Channel port" , "fish" , "There'll be blue clouds over the white cliffs here" , "Kentish port" , "Sort of sole" .)
