Rays created by Academician an idiot restored (9)
I believe the answer is:
radiation
'rays created' is the definition.
I can't judge whether this definition defines the answer.
'academician an idiot restored' is the wordplay.
'academician' becomes 'ra'.
'restored' indicates anagramming the letters.
'an'+'idiot'='anidiot'
'anidiot' is an anagram of 'diation'.
'ra'+'diation'='RADIATION'
'by' is the link.
Can you help me to learn more?
(Other definitions for radiation that I've seen before include "Energy emitted by eg the sun" , "Transmission of energy" , "given out with mobile phones?" , "Harmful waves" , "Nuclear emissions" .)
