Crazy Cathie left. It's about the right conduct (7)
I believe the answer is:
ethical
'about the right conduct' is the definition.
I can't tell whether this definition defines the answer.
'crazy cathie left' is the wordplay.
'crazy' is an anagram indicator.
'left' becomes 'l' (common abbreviation).
'cathie' is an anagram of 'ethica'.
'ethica'+'l'='ETHICAL'
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for ethical that I've seen before include "Morally correct, in accordance with principles" , "Conforming to accepted standards of behaviour" , "Morally correct, in accordance with professional standards" , "Principled (behaviour)" , "lt's available on prescription only" .)
