Hurt overthrowing most of city (4)
I believe the answer is:
maim
'hurt' is the definition.
(I know that maim is a more specific form of the action injure)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for maim that I've seen before include "Injure and cripple" , "Wound and permanently disfigure" , "Wound so that part of body is permanently damaged" , "Injure (a person), causing permanent disability" , "Injure seriously, leaving permanent damage" .)
