Bishop to read about Van Dyke, say (5)
I believe the answer is:
beard
'van dyke say' is the definition.
I can't tell whether this defines the answer.
'bishop to read about' is the wordplay.
'bishop' becomes 'b' (chess abbreviation).
'about' indicates anagramming the letters.
'read' with letters rearranged gives 'eard'.
'b'+'eard'='BEARD'
Can you help me to learn more?
(Other definitions for beard that I've seen before include "Facial growth" , "hair extension" , "SECOND PART OF 14" , "Goatee, for instance" , "Oppose with effrontery" .)
