Renovated spindle daughter finds brilliant (8)
I believe the answer is:
splendid
'brilliant' is the definition.
(I've seen this before)
'renovated spindle daughter' is the wordplay.
'renovated' is an anagram indicator.
'daughter' becomes 'd'.
'spindle' anagrammed gives 'splendi'.
'splendi'+'d'='SPLENDID'
'finds' acts as a link.
(Other definitions for splendid that I've seen before include "Wonderful" , "Very fine, quite glorioous" , "Excellent, magnificent" , "Wicked" , "Superb" .)
