Disdain? Not for allure (8)
I believe the answer is:
contempt
'disdain?' is the definition.
(thesaurus)
'not for allure' is the wordplay.
'not' becomes 'con' (I've seen this in other clues).
'for' says to put letters next to each other.
'allure' becomes 'tempt' ('tempt' can be a synonym of 'allure').
'con'+'tempt'='CONTEMPT'
(Other definitions for contempt that I've seen before include "Feeling of dislike for, perhaps of court?" , "Open disrespect, to a court, say" , "Scornful feeling" , "The feeling of despising a person" , "Wilful disrespect of authority" .)
