Ironside disturbed by scorn (8)
I believe the answer is:
derision
'scorn' is the definition.
(I've seen this in another clue)
'ironside disturbed' is the wordplay.
'disturbed' is an anagram indicator (the order of letters is disturbed).
'ironside' is an anagram of 'DERISION'.
'by' is the link.
(Other definitions for derision that I've seen before include "'Ridicule, contempt (8)'" , "Mockery, ridicule" , "Contemptuous ridicule" , "Ironside (anag) - mockery" , "Contemptuous mockery" .)
