One fired from shop is to litigate (6)
I believe the answer is:
pistol
'one fired' is the definition.
I can't tell whether this defines the answer.
'from shop is to litigate' is the wordplay.
'from' says the answer is hidden in the clue.
'PISTOL' can be found hidden inside 'shop is to litigate'.
Can you help me to learn more?
(Other definitions for pistol that I've seen before include "Piece" , "Arm" , "potential killer?" , "A small hand-gun" , "Shakespearean character" .)
