Because the rendering is included in one’s dislikes (9)
I believe the answer is:
'one's dislikes' is the definition.
'aversions' can be an answer for 'dislikes' (aversion is a kind of dislike). I'm not certain of the 'one's' bit.
'because the rendering is included' is the wordplay.
'because' becomes 'as' (I've seen this in other clues).
'the rendering' becomes 'version' ('version' can be a synonym of 'rendering').
'is included' means one lot of letters goes inside another.
'as' enclosing 'version' is 'AVERSIONS'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for aversions that I've seen before include "Hates" , "Dislikes" .)
