Neglect daughter - poor Susie! (6)
I believe the answer is:
disuse
'neglect' is the definition.
(both can mean a state of disrepair)
'daughter poor susie' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'poor' indicates an anagram.
'susie' with letters rearranged gives 'isuse'.
'd'+'isuse'='DISUSE'
(Other definitions for disuse that I've seen before include "Issued (anag)" , "Neglect; desuetude" , "State of not being employed" , "Fall into this state to be unemplyed? (6)." , "Neglect; abandonment" .)
