Corrected derives from it (7)
I believe the answer is:
revised
'corrected derives from it' is the definition.
I can't judge whether this definition defines the answer.
'corrected derives' is the wordplay.
'corrected' indicates anagramming the letters.
'derives' anagrammed gives 'REVISED'.
Can you help me to learn more?
(Other definitions for revised that I've seen before include "Altered" , "Prepared for exams" , "Reviewed and amended" , "Studied anew" , "Changed and improved" .)
