Wood used for bows (3)
I believe the answer is:
yew
'wood used for bows' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for yew that I've seen before include "Evergreen shrub" , "'Evergreen tree, reddish-brown wood (3)'" , "Wood for archers" , "Conifer" , "This tree grows in churchyard" .)
