Charge a lot for fodder (4)
I believe the answer is:
feed
'fodder' is the definition.
(thesaurus)
'charge a lot' is the wordplay.
'charge' becomes 'fee' (fee is a kind of charge**).
'a lot' becomes 'd'.
'fee'+'d'='FEED'
'for' is the link.
(Other definitions for feed that I've seen before include "Take food" , "Given payment" , "Give food to; eat" , "Provide food" , "forage" .)
