Neat wood (6)
I believe the answer is:
spruce
I believe this clue is a double definition.
'neat' is the first definition.
('spruce' can be a synonym of 'neat')
'wood' is the second definition.
(spruce is a kind of wood)
(Other definitions for spruce that I've seen before include "Neat and dapper tree" , "Smart, trim" , "tree with needle-like leaves" , "Christmas tree, perhaps" , "perfect condition" .)
