Rifle shot misses horse? That'll raise spirits! (4)
I believe the answer is:
lift
'that'll raise spirits' is the definition.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lift that I've seen before include "Pick up" , "Raise, elevate" , "remove" , "Raise the vertical conveyor" , "Free ride" .)
