Key flavour is hidden in repugnance (8)
I believe the answer is:
distaste
'repugnance' is the definition.
(I've seen this in another clue)
'key flavour is' is the wordplay.
I cannot really understand how this works, but
'key' could be 'd' (musical key) and 'd' is found in the answer.
'flavour' could be 'taste' (I've seen this before) and 'taste' is present in the answer.
'is' is within the answer.
No letters remain.
This explanation may well be incorrect...
'hidden in' is the link.
Can you help me to learn more?
(Other definitions for distaste that I've seen before include "Not liking" , "Repugnance" , "Loathing" , "Dislike of something unsavoury" , "Feeling of dislike or aversion" .)
