A charge for a trophy (5)
I believe the answer is:
award
'trophy' is the definition.
(I've seen this before)
'a charge for a' is the wordplay.
'a charge' becomes 'ward' (both can mean a child in one's care).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'ward' after 'a' is 'AWARD'.
(Other definitions for award that I've seen before include "Adjudge" , "Give officially as prize or payment" , "Present - prize" , "Trophy or medal, for example" , "Give, grant" .)
