Like a neck twisted sideways (7)
I believe the answer is:
askance
'sideways' is the definition.
(I've seen this in another clue)
'like a neck twisted' is the wordplay.
'like' becomes 'as'.
'twisted' is an anagram indicator.
'a'+'neck'='aneck'
'aneck' is an anagram of 'kance'.
'as'+'kance'='ASKANCE'
(Other definitions for askance that I've seen before include "Distrustfully" , "(Consider) with suspicion - sideways" , "(Look) obliquely with mistrust" , "Indirectly" , "Look like this to show suspicion" .)
