Provide soldier with victory (4)
I believe the answer is:
give
'provide' is the definition.
(I know that give is a type of provide)
'soldier with victory' is the wordplay.
'soldier' becomes 'gi' (GI can mean a US soldier).
'with' means one lot of letters go next to another.
'victory' becomes 'VE' (VE is short for Victory in Europe).
'gi'+'ve'='GIVE'
(Other definitions for give that I've seen before include "Yield - supply" , "Bestow or donate" , "Award" , "Hold out" , "old-fashioned shackle" .)
