Instead changed the first to "repugnance" (8)
I believe the answer is:
distaste
'repugnance' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for distaste that I've seen before include "Loathing" , "Mild horror" , "Mild dislike, aversion" , "Feeling of dislike - unsavoury?" , "Adverse reaction" .)
