Beloved daughter hearing organ (4)
I believe the answer is:
dear
'beloved' is the definition.
('dear' can be a synonym of 'beloved')
'daughter hearing organ' is the wordplay.
'daughter' becomes 'd'.
'hearing organ' becomes 'ear' (I've seen this before).
'd'+'ear'='DEAR'
(Other definitions for dear that I've seen before include "polite form of address" , "Beloved or costly" , "Expensive -- honey" , "Overpriced" , "Honey - costly" .)
