Small country on radar in revolution (7)
I believe the answer is:
andorra
'small country' is the definition.
'andorra' can be an answer for 'country' (I've seen this before). I'm unsure of the 'small' bit.
'on radar in revolution' is the wordplay.
'in revolution' indicates anagramming the letters.
'on'+'radar'='onradar'
'onradar' with letters rearranged gives 'ANDORRA'.
Can you help me to learn more?
(Other definitions for andorra that I've seen before include "Catalan state" , "Small European country" , "mountainous country" , "Mountainous principality of southwest Europe" , "microstate" .)
