Spoils the nearby world (4)
I believe the answer is:
mars
This could be a double definition.
'spoils' is the first definition.
('mar' can be a synonym of 'spoil')
'nearby world' is the second definition.
'Mars' can be an answer for 'world' (another planet). I'm not sure about the 'nearby' bit.
'the' is the link.
Can you help me to learn more?
(Other definitions for mars that I've seen before include "one associated with war" , "part of suite" , "Possibly pollutes" , "Roman war god; planet" , "Next planet out" .)
