Pawnbroker’s corrupt removing article (5)
I believe the answer is:
uncle
'pawnbroker's' is the definition.
(old-fashioned term for a pawnbroker)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for uncle that I've seen before include "Male relation; pawnbroker" , "Grandfather's son" , "Brother of one's parent" , "Sam, perhaps" , "Pawnbroker's nickname" .)
