What edition embodies couldn't stand (5)
I believe the answer is:
'couldn't stand' is the definition.
(I've seen this in another clue)
'what edition embodies' is the wordplay.
'embodies' indicates the answer is hidden within the clue.
'HATED' is hidden in the letters of 'what edition'.
(Other definitions for hated that I've seen before include "Unpopular" , "gave stinking review to?" , "Seriously disliked" , "Heartily disliked" , "couldn't stand" .)
