Feel contempt for (7)
I believe the answer is:
despise
'feel contempt for' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for despise that I've seen before include "Scorn; loathe" , "Loathe, look down on" , "Feel contempt for (someone/something)" , "Hate, disdain" , "Hold in contempt" .)
