No, I engendered flipping contempt (8)
I believe the answer is:
derision
'contempt' is the definition.
(I've seen this before)
'no i engendered flipping' is the wordplay.
'engendered' becomes 'sired' ('sire' can be a synonym of 'engender').
'flipping' shows that the letters should be reversed in order.
'no'+'i'+'sired'='noisired'
'noisired' backwards is 'DERISION'.
(Other definitions for derision that I've seen before include "Mockery, ridicule" , "Contemptuous mockery" , "'Ridicule, contempt (8)'" , "Contemptuous ridicule" , "Ironside (anag) - mockery" .)
