Who deals with English nonsense the author had written up? (6)
I believe the answer is:
editor
'who' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for editor that I've seen before include "one to give some publicity?" , "Magazine head" , "Do tire out the press person" , "Director of publication" , "Reviser" .)
