Traces out some sugar (6)
I believe the answer is:
caster
'some sugar' is the definition.
'traces out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'traces' is an anagram of 'CASTER'.
(Other definitions for caster that I've seen before include "Swivelling wheel (E, not O)" , "Crates with kind of fine sugar" , "Founder; type of 12 Ac" , "One who throws something" , "Small swivelling wheel on furniture" .)
