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 really understand how this works, but
an anagram of 'feel' is 'flee' which is present in the answer.
'see' could be 'c' (the word for the letter, according to Chambers) and 'c' is present in the answer.
'chap' could be 'ed' (short for Edward) and 'ed' is located in the answer.
This accounts for all the letters.
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" .)
