Loathing an interpretation (8)
I believe the answer is:
aversion
'loathing' is the definition.
(I've seen this in another clue)
'an interpretation' is the wordplay.
'an' becomes 'a'.
'interpretation' becomes 'version' (synonyms).
'a'+'version'='AVERSION'
(Other definitions for aversion that I've seen before include "horror" , "Dislike, hatred" , "A strong dislike or repugnance" , "Strong dislike for, makes you look away" , "A strong dislike for something - turn away from it" .)
