Was oblivious to redoing wrong! (7)
I believe the answer is:
ignored
'was oblivious' is the definition.
I can't judge whether this defines the answer.
'redoing wrong' is the wordplay.
'wrong' is an anagram indicator.
'redoing' anagrammed gives 'IGNORED'.
'to' is the link.
Can you help me to learn more?
(Other definitions for ignored that I've seen before include "Passed over" , "Snubbed" , "Neglected" , "Paid no heed" , "Paid no attention to" .)
