Daughter at back of house, underdog not half harassed (7)
I believe the answer is:
hounded
'harassed' is the definition.
(I've seen this before)
'daughter at back of house underdog not half' is the wordplay.
'daughter' becomes 'd'.
'at back of' is a charade indicator (letters next to each other).
'house' becomes 'ho' (abbreviation for house).
'not half' means to take half the letters.
'underdog' halved is 'unde'.
'ho'+'unde'='hounde'
'd' after 'hounde' is 'HOUNDED'.
(Other definitions for hounded that I've seen before include "Dogged" , "Badgered" , "harassed" .)
