Earth pulverised (6)
I believe the answer is:
ground
I believe this is a double definition.
'earth' is the first definition.
(I know that earth can be written as ground)
'pulverised' is the second definition.
(past tense of 'grind')
(Other definitions for ground that I've seen before include "Land - crushed to powder" , "Stop (a pilot) flying" , "Pulverised; land" , "Base; reason" , "Earth; stadium" .)
