Sparkle in rearranged court case (9)
I believe the answer is:
coruscate
'sparkle' is the definition.
(I've seen this before)
'rearranged court case' is the wordplay.
'rearranged' indicates an anagram.
'court'+'case'='courtcase'
'courtcase' is an anagram of 'CORUSCATE'.
'in' is the link.
(Other definitions for coruscate that I've seen before include "Glitter or sparkle in court case" , "Flash, sparkle" , "Show flashes of brilliance" , "Shimmer and flash in court case" .)
