Schoolboy possibly rejecting award from The Sun (5)
I believe the answer is:
solar
'from the sun' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for solar that I've seen before include "like a star" , "Concerning the sun" , "sunny?" , "chamber in old house" , "of heavenly body" .)
