Be brilliant (11)

I believe the answer is:

scintillate

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">be brilliant</span>' is the definition.<br/ ><span class="explanation-format__explanation">(thesaurus)</span><br/ ><br/ >This is the entire clue.<br/ ></span>

(Other definitions for scintillate that I've seen before include "Flash, sparkle" , "Emit flashes of light" , "Sparkle - elastic lint (anag)" , "Coruscate" , "give sparkling performance" .)

I've seen this clue in The Guardian.
