Feel disgust for (6)
I believe the answer is:
loathe
'feel disgust for' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for loathe that I've seen before include "Can't stand" , "To heal (anag)" , "Cordially dislike, despise" , "cannot stand" , "Abhor, abominate" .)
