Dirty article repelled pawnbroker (5)
I believe the answer is:
uncle
'pawnbroker' is the definition.

I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for uncle that I've seen before include "Family relative" , "Law enforcement body" , "Brother of one's parent" , "Pawnbroker (sl.)" , "Pawnbroker's nickname" .)
