Eccentric apprised of Cold War's cause (5,2,7)

I believe the answer is:

apple of discord

I'm a little stuck... Click here to teach me more about this clue!

'war's cause' is the definition.
The definition suggests a singular noun which matches the answer.

'eccentric apprised of cold' is the wordplay.
'eccentric' indicates anagramming the letters.
'apprised'+'of'+'cold'='apprisedofcold'
'apprisedofcold' anagrammed gives 'APPLE OF DISCORD'.

Can you help me to learn more?
