Weapon which would be redundant with point moved to the end (5)
I believe the answer is:
spear
'weapon' is the definition.
(spear is a kind of weapon)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for spear that I've seen before include "Primitive weapon" , "Long pointed weapon" , "Impale" , "mint may be added" , "Spike" .)
