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' is an anagram indicator (out can mean wrong or inaccurate).
'take' with letters rearranged gives '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" .)
