Clever bishop? Correct! (6)
I believe the answer is:
bright
'clever' is the definition.
(bright can mean clever or gifted)
'bishop? correct' is the wordplay.
'bishop?' becomes 'B' (chess abbreviation).
'correct' becomes 'right' (right can mean correct).
'b'+'right'='BRIGHT'
(Other definitions for bright that I've seen before include "Radiant or intelligent" , "Clever - shining - sunny" , "Intelligent; vivid" , "Vivid - promising - smart" , "Illuminated" .)
