Guns, and where one might find them (4)
I believe the answer is:
arms
'guns' is the definition.
(I've seen this in another clue)
'where one might find them' is the wordplay.
I cannot really understand how this works, but
'one' could be 'a' (a thing is one thing) and 'a' is found within the answer.
The remaining letters 'rms' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for arms that I've seen before include "Blazonry; weaponry" , "Limbs of war" , "Appendages" , "See 11" , "Weapons and limbs" .)
