What emerges is a new lustre (6)
I believe the answer is:
result
'what emerges' is the definition.
I can't tell whether this definition defines the answer.
'new lustre' is the wordplay.
'new' indicates an anagram.
'lustre' with letters rearranged gives 'RESULT'.
'is a' is the link.
Can you help me to learn more?
(Other definitions for result that I've seen before include "Effect of lustre" , "Ulster (anag) - outcome" , "Rustle (anag.)" , "'Outcome, upshot (6)'" , "End - issue" .)
