Arrogance of Mann shunning human nature perversely (7)
I believe the answer is:
hauteur
'arrogance' is the definition.
(thesaurus)
'mann shunning human nature perversely' is the wordplay.
'shunning' suggests deleting specific letters.
'perversely' indicates an anagram.
'human'+'nature'='humannature'
'humannature' with 'mann' taken out is 'huature'.
'huature' with letters rearranged gives 'HAUTEUR'.
'of' acts as a link.
(Other definitions for hauteur that I've seen before include "Overbearing arrogance" , "Arrogant disdain" , "Disdainful pride or snobbery" , "Proud arrogance" , "Proud disdain" .)
