Daughter in prison, revealing bum (5)
I believe the answer is:
cadge
'bum' is the definition.
(both can mean to beg someone for something)
'daughter in prison' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'in' is an insertion indicator.
'prison' becomes 'cage' (I've seen this before).
'd' inserted into 'cage' is 'CADGE'.
'revealing' acts as a link.
(Other definitions for cadge that I've seen before include "Scrounge (money, etc)" , "Try to get (something) without paying" , "get free" , "Get by begging" , "Get money by sponging" .)
