Starts shooting remarks as weapons (6)
I believe the answer is:
swords
'weapons' is the definition.
(sword is a kind of weapon)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for swords that I've seen before include "Fighting blades" , "Thrusting weapons" , "Weapons; a Tarot suit" , "Eg, rapiers, sabres" , "Bladed weapons in north Dublin" .)
