Result may be a shine (6)
I believe the answer is:
lustre
'a shine' is the definition.
(I know that lustre is a type of shine)
'result may be' is the wordplay.
'may be' is an anagram indicator.
'result' is an anagram of 'LUSTRE'.
(Other definitions for lustre that I've seen before include "Period" , "Gloss - type of pottery" , "Soft brightness or glory" , "Sheen or renown" , "Brilliant quality in a material, porcelain, etc" .)
