Contempt shown by inspector, attorney caught in wrongdoing (7)
I believe the answer is:
disdain
'contempt' is the definition.
('disdain' can be a synonym of 'contempt')
'inspector attorney caught in wrongdoing' is the wordplay.
'inspector' becomes 'di' (I've seen this in other clues).
'attorney' becomes 'da' (District Attorney).
'caught in' is an insertion indicator.
'wrongdoing' becomes 'sin' (sin is a kind of wrongdoing**).
'da' placed into 'sin' is 'sdain'.
'di'+'sdain'='DISDAIN'
'shown by' acts as a link.
(Other definitions for disdain that I've seen before include "no respect" , "Scorn - feeling of superiority" , "Contempt for something unworthy of notice" , "cold shoulder" , "Think (something) unworthy" .)
