Wood, you said? (3)
I believe the answer is:
yew
'wood' is the definition.
(I know that yew is a type of wood)
'you said?' is the wordplay.
'said?' shows a homophone (sound like).
'you' sounds like 'YEW'.
(Other definitions for yew that I've seen before include "Coniferous tree" , "Common churchyard feature" , "Evergreen tree with dark leaves and red berries" , "Longbow wood" , "Wood for bows" .)
