Relief for one said to have been duped (7)
I believe the answer is:
succour
'relief' is the definition.
(I know that relief can be written as succour)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for succour that I've seen before include "helping hand" , "Render assistance to" , "Assistance, support" , "Isolated" , "Give assistance in time of difficulty" .)
