Asparagus shoot (5)
I believe the answer is:
spear
'asparagus shoot' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for spear that I've seen before include "Simple weapon" , "Weapon to throw" , "Javelin or harpoon" , "Weapon; asparagus stem" , "Asparagus shoot" .)
