Applying logic makes a sinner go wrong (9)
I believe the answer is:
reasoning
'applying logic' is the definition.
I can't tell whether this defines the answer.
'a sinner go wrong' is the wordplay.
'wrong' is an anagram indicator.
'a'+'sinner'+'go'='asinnergo'
'asinnergo' is an anagram of 'REASONING'.
'makes' acts as a link.
Can you help me to learn more?
(Other definitions for reasoning that I've seen before include "Thinking coherently and logically" , "sense?" , "Logic" , "argument" , "Logical thought process" .)
