Take out timber (4)
I believe the answer is:
teak
'timber' is the definition.
(I've seen this in other clues)
'take out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'take' anagrammed gives 'TEAK'.
(Other definitions for teak that I've seen before include "A SE Asian hardwood" , "Hardwood found naturally in the Far East" , "Valuable, dense wood" , "Indian hardwood" , "Quality timber" .)
