Deceived where duke escaped cunningly (7)
I believe the answer is:
deluded
'deceived' is the definition.
('delude' can be a synonym of 'deceive')
'duke escaped cunningly' is the wordplay.
I cannot really understand how this works, but
'duke' could be 'd' (abbreviation) and 'd' is found within the answer.
'escaped' could be 'eluded' (eluding is a kind of escaping) and 'eluded' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'where' is the link.
Can you help me to learn more?
(Other definitions for deluded that I've seen before include "Duped or misled" , "hoodwinked" , "Deceived or misled" , "Deceived by nonsense" , "Deceived into false belief" .)
