Dad is upset, in feeling of contempt (7)
I believe the answer is:
disdain
'feeling of contempt' is the definition.
(I've seen this in another clue)
'dad is upset in' is the wordplay.
'upset' indicates an anagram.
'dad'+'is'='dadis'
'dadis' with letters rearranged gives 'disda'.
'disda'+'in'='DISDAIN'
(Other definitions for disdain that I've seen before include "Hauteur" , "Look down on" , "Contempt for something unworthy of notice" , "Haughtiness" , "no respect" .)
