Like the nasty fault he corrected (7)
I believe the answer is:
hateful
'like the nasty' is the definition.
I can't tell whether this defines the answer.
'fault he corrected' is the wordplay.
'corrected' indicates an anagram.
'fault'+'he'='faulthe'
'faulthe' is an anagram of 'HATEFUL'.
Can you help me to learn more?
(Other definitions for hateful that I've seen before include "Loathsome" , "Abhorrent" , "repellent" , "Detestable" , "Dreadful" .)
