Delightful first couple off providing weapons (6)
I believe the answer is:
arming
'providing weapons' is the definition.
'arming' can be an answer for 'providing' (arming is a kind of providing). I am unsure of the 'weapons' bit.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for arming that I've seen before include "Supplying weapons" , "Equipping for war" , "Providing with weapons" , "Equipping with weapons" , "Taking up weapons" .)
