Weapon that underpins a stabbing risk (7)
I believe the answer is:
bayonet
'weapon' is the definition.
(I know that bayonet is a type of knife)
'that underpins a stabbing risk' is the wordplay.
I cannot quite understand how this works, but
'that' could be 'yon' (archaic term meaning 'that') and 'yon' is found within the answer.
'a' is within the answer.
'risk' could be 'bet' (I've seen this in another clue) and 'bet' is located in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bayonet that I've seen before include "Type of light bulb fitting" , "Lethal Weapon" , "Pointed weapon" , "Neat boy (anag.)" , "Kind of knife attached to a rifle" .)
