Rising in South calling for immediate action (9)
I believe the answer is:
insurgent
'rising' is the definition.
(I've seen this before)
'in south calling for immediate action' is the wordplay.
I cannot quite understand how this works, but
'in' is present in the answer.
'south' could be 's' (abbreviation) and 's' is found in the answer.
'calling' could be 'urge' (I've seen this in another clue) and 'urge' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for insurgent that I've seen before include "Unresting like a rebel" , "Revolting" , "freedom fighter" , "Rebel, revolutionary" , "rising" .)
