He presents Joe with one piece of silver (5)
I believe the answer is:
giver
'he' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'joe with one piece of silver' is the wordplay.
'joe' becomes 'GI' (GI Joe).
'with' is a charade indicator (letters next to each other).
'one piece of silver' becomes 'ver' (I can't explain this - if you can you should give a lot more credence to this answer).
'gi'+'ver'='GIVER'
'presents' is the link.
Can you help me to learn more?
(Other definitions for giver that I've seen before include "Present source" , "Donor" , "Bestower" , "presenter" .)
