Take out some wood (4)
I believe the answer is:
teak
'some wood' is the definition.
(type of timber)
'take out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'take' is an anagram of 'TEAK'.
(Other definitions for teak that I've seen before include "Strong heavy wood of an Asian tree" , "Type of tree" , "E. Indies hardwood" , "Hardwood found naturally in the Far East" , "Hard wood for Kate" .)
