Loathing awfully staid set (8)
I believe the answer is:
distaste
'loathing' is the definition.
(I've seen this before)
'awfully staid set' is the wordplay.
'awfully' indicates anagramming the letters.
'staid'+'set'='staidset'
'staidset' anagrammed gives 'DISTASTE'.
(Other definitions for distaste that I've seen before include "Abhorrence" , "Feeling of dislike - unsavoury?" , "lack of relish?" , "Negative feeling" , "Adverse reaction" .)
