Specified soldier with victory over knight (5)
I believe the answer is:
given
'specified' is the definition.
(similar in meaning)
'soldier with victory over knight' is the wordplay.
'soldier' becomes 'gi' (GI can mean a US soldier).
'with' says to put letters next to each other.
'victory' becomes 'VE' (VE is short for Victory in Europe).
'over' says to put letters next to each other.
'knight' becomes 'N' (chess abbreviation).
'gi'+'ve'+'n'='GIVEN'
(Other definitions for given that I've seen before include "Awarded" , "Handed over; an 18 dn" , "Specified, stated" , "Specified - granted" , "Accepted as true" .)
