A charge for medal, say (5)
I believe the answer is:
award
'for medal say' is the definition.
(medal is a kind of award)
'a charge' is the wordplay.
'charge' becomes 'ward' (both can mean a child in one's care).
'a'+'ward'='AWARD'
(Other definitions for award that I've seen before include "They are disinclined to work" , "settlement" , "Give, grant" , "Grant made by a court of law" , "Grant - prize" .)
