Single paw used to fight with (6)
I believe the answer is:
weapon
'single' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for weapon that I've seen before include "Means of fighting" , "Implement to injure or kill" , "Instrument of war" , "Thing used to hurt, like gun, knife, bomb etc" , "club, perhaps" .)
