The staidest form of dislike (8)
I believe the answer is:
distaste
'dislike' is the definition.
(I know that distaste is a type of dislike)
'the staidest form' is the wordplay.
'form' indicates anagramming the letters.
'staidest' is an anagram of 'DISTASTE'.
'of' acts as a link.
(Other definitions for distaste that I've seen before include "lack of relish?" , "Mild dislike, aversion" , "Feeling of dislike - unsavoury?" , "Antipathy, aversion" , "Feeling of dislike or aversion" .)
