Weapon that a sergeant wields (5)
I believe the answer is:
taser
'weapon' is the definition.
(taser is a type of weapon)
'that a sergeant wields' is the wordplay.
'TASER' is hidden within the letters.
However, I'm not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for taser that I've seen before include "Weapon firing electrified darts; stare (anag.)" , "Electrical weapon" , "police weapon introduced" , "Gun firing electrified barbs" , "Stunning weapon" .)
