Charge daughter for fodder (4)
I believe the answer is:
feed
'for fodder' is the definition.
(fodder is animal feed)
'charge daughter' is the wordplay.
'charge' becomes 'fee' (fee is a kind of charge).
'daughter' becomes 'd' (genealogical abbreviation).
'fee'+'d'='FEED'
(Other definitions for feed that I've seen before include "take grub" , "comedian's assistant" , "forage" , "Provide food" , "Take food" .)
