Feel disturbed when you see a chap robbed (7)
I believe the answer is:
fleeced
'robbed' is the definition.
('fleece' can be a synonym of 'rob')
'feel disturbed when you see a chap' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'feel' is 'flee' which is within the answer.
'see' could be 'c' (the word for the letter, according to Chambers) and 'c' is located in the answer.
'chap' could be 'ed' (short for Edward) and 'ed' 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 fleeced that I've seen before include "woolly coat?" , "Robbed by trickery, like sheep" , "Swindled" , "Taken to the cleaners" , "Taken for a ride" .)
