Odd result? It's brilliant! (6)
I believe the answer is:
lustre
'it's brilliant' is the definition.
I can't judge whether this definition defines the answer.
'odd result?' is the wordplay.
'odd' is an anagram indicator.
'result' with letters rearranged gives 'LUSTRE'.
Can you help me to learn more?
(Other definitions for lustre that I've seen before include "Soft brightness or glory" , "Radiance; reflective surface" , "Rustle with shine on surface" , "Rustle up the sheen" , "Brilliant quality in a material, porcelain, etc" .)
