Duck seen in English Channel going wrong way! (5)
I believe the answer is:
evade
'duck' is the definition.
(synonyms)
'english channel going wrong way' is the wordplay.
'english' becomes 'e' (abbreviation).
'channel' becomes 'dave' (I've seen this before).
'going wrong way' says the letters should be written backwards.
'e'+'dave'='edave'
'edave' reversed gives 'EVADE'.
'seen in' is the link.
(Other definitions for evade that I've seen before include "Hedge" , "Escape (something)" , "Dodge (taxes)" , "bypass" , "Slyly escape" .)
