Orals set about a star (5)
I believe the answer is:
solar
'about a star' is the definition.
I can't tell whether this definition defines the answer.
'orals set' is the wordplay.
'set' is an anagram indicator (instruction to set the letters).
'orals' is an anagram of 'SOLAR'.
Can you help me to learn more?
(Other definitions for solar that I've seen before include "chamber in old house" , "Using the energy of the sun" , "like a star" , "Powered by the sun" , "Relating to our star" .)
