Points to one of five kids as being bright (6)
I believe the answer is:
sequin
'kids as being bright' is the definition.
I can't judge whether this definition defines the answer.
'points to one of five' is the wordplay.
'points' becomes 'se' (two compass points).
'to one of five' becomes 'quin' (short for quintuplet, one of five children).
'se'+'quin'='SEQUIN'
Can you help me to learn more?
(Other definitions for sequin that I've seen before include "Glittery decoration" , "Small shiny disc for decoration" , "that sparkles" , "Shiny decoration for clothes" , "possibly a gold disc" .)
