Trace out container (5)
I believe the answer is:
crate
'container' is the definition.
(crate is a kind of container)
'trace out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'trace' anagrammed gives 'CRATE'.
(Other definitions for crate that I've seen before include "Wooden box" , "Packing container" , "heap" , "old banger" , "Wooden container" .)
