Wood used in bow-making (3)
I believe the answer is:
yew
'wood used in bow-making' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for yew that I've seen before include "Common churchyard feature" , "'Evergreen tree, reddish-brown wood (3)'" , "Evergreen tree with narrow dark-green leaves and red berries" , "Bow wood" , "Conifer" .)
