In the military, I help part of this country after revolution (5)
I believe the answer is:
india
'in the military i help part of this country after revolution' is the definition.
'India' can be an answer for 'country' (India is an example). I'm not sure about the remainder of the definition.
'i help part of this country after revolution' is the wordplay.
'help' becomes 'aid' (synonyms).
'part of this country' becomes 'n' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'after revolution' says the letters should be written in reverse (letters revolve back).
'aid'+'n'='aidn'
'aidn' reversed gives 'ndia'.
'i'+'ndia'='INDIA'
Can you help me to learn more?
(Other definitions for india that I've seen before include "Populous Asian country" , "Commonwealth state" , ""Bharat", locally" , "where to ring for help?" , "Big country" .)
