Wherein half the army is at the Western Front (3)
I believe the answer is:
war
'wherein half the army is at the western front' is the definition.
I can't judge whether this definition defines the answer.
'half the army is at the western front' is the wordplay.
'half the' means to take half the letters.
'is at' means one lot of letters go next to another (I've seen this in other clues).
'front' suggests taking the first letters.
The first letter of 'western' is 'w'.
'army' halved is 'ar'.
'ar' after 'w' is 'WAR'.
Can you help me to learn more?
(Other definitions for war that I've seen before include "Fight" , "State of armed conflict" , "series of engagements" , "Period of hostilities" , "Large-scale conflict" .)
