Injured? Not hard with a sword, maybe (5)
I believe the answer is:
armed
'injured?' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for armed that I've seen before include "ready to fight" , "Prepared for attack" , "Like Mars" , "Dream about carrying weapons" , "Equipped with weapons" .)
