Javelin or lance (5)
I believe the answer is:
spear
I believe this clue is a double definition.
'javelin' is the first definition.
(I've seen this in another clue)
'lance' is the second definition.
(I know that lance can be written as spear)
(Other definitions for spear that I've seen before include "Stabbing, throwing, weapon" , "Old weapon" , "Weapon to throw" , "asparagus for example" , "stick" .)
