Editor turning stingy leads to our sort of attitude (9)
I believe the answer is:
demeanour
'sort of attitude' is the definition.
(I know that demeanour is a type of attitude)
'editor turning stingy leads to our' is the wordplay.
'editor' becomes 'ed' (abbreviation).
'turning' says the letters should be written in reverse.
'stingy' becomes 'mean' (similar in meaning).
'leads to' is a charade indicator (letters next to each other).
'ed' in reverse letter order is 'de'.
'de'+'mean'+'our'='DEMEANOUR'
(Other definitions for demeanour that I've seen before include "Behaviour" , "Conduct" , "Manner of behaving towards others" , "Look" , "Enamoured of the way a person behaves" .)
