Award to a soldier on a day of victory (4)
I believe the answer is:
give
'award' is the definition.
(I've seen this before)
'a soldier on a day of victory' is the wordplay.
'a soldier' becomes 'gi' (government issue or general issue**).
'on' means one lot of letters go next to another.
'a day of victory' becomes 've'.
'gi'+'ve'='GIVE'
'to' is the link.
(Other definitions for give that I've seen before include "concede" , "Award" , "Donate, grant" , "Yield, produce" , "Make a present of" .)
