Endless report of revolution in east Alabama (7)
I believe the answer is:
eternal
'endless' is the definition.
(I know that endless can be written as eternal)
'report of revolution in east alabama' is the wordplay.
'report of revolution' becomes 'tern' (I can't explain this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'east' becomes 'e' (abbreviation).
'alabama' becomes 'al' (abbreviation).
'e'+'al'='eal'
'tern' inserted within 'eal' is 'ETERNAL'.
Can you help me to learn more?
(Other definitions for eternal that I've seen before include "Never failing" , "Seemingly without end" , "carrying on endlessly" , "Such a city is Rome" , "Forever and always" .)
