Throw out crude revolutionary period of conflict (7)
I believe the answer is:
wartime
'period of conflict' is the definition.
'wartime' can be an answer for 'period' (wartime is a kind of period). I'm unsure of the 'of conflict' bit.
'throw out crude revolutionary' is the wordplay.
'throw out' becomes 'emit' (I've seen this before).
'crude' becomes 'raw' (synonyms).
'revolutionary' shows that the letters should be reversed in order.
'emit'+'raw'='emitraw'
'emitraw' back-to-front is 'WARTIME'.
Can you help me to learn more?
(Another definition for wartime that I've seen is " Eg, nineteen thirty nine to nineteen fourty five".)
