Scam to entice one held in disdain (8)
I believe the answer is:
contempt
'disdain' is the definition.
(I know that disdain can be written as contempt)
'scam to entice' is the wordplay.
'scam' becomes 'con' (both can mean a fraudulent scheme).
'to entice' becomes 'tempt' ('tempt' can be a synonym of 'entice').
'con'+'tempt'='CONTEMPT'
'one held in' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for contempt that I've seen before include "Disregard for the rules of a court of law" , "Disdain or disrespect, perhaps or court" , "Offence of disrespect in court" , "Feeling of dislike for, perhaps of court?" , "Feeling of disdain, sometimes of court" .)
