Sparkle in castle lit for a change (11)

I believe the answer is:

scintillate

'sparkle' is the definition.
(to scintillate is to sparkle or gleam)

'in castle lit for a change' is the wordplay.
'for a change' is an anagram indicator.
'in'+'castle'+'lit'='incastlelit'
'incastlelit' with letters rearranged gives 'SCINTILLATE'.

(Other definitions for scintillate that I've seen before include "Glitter" , "Twinkle - sparkle" , "Flash, sparkle" , "Coruscate" , "give sparkling performance" .)

I've seen this clue in The Times.
