Escape return of some dreaded aversion (5)
I believe the answer is:
evade
'escape' is the definition.
(I know that evade is a type of escape)
'return of some dreaded aversion' is the wordplay.
'return of' shows that the letters should be reversed in order.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'edave' is hidden within 'dreaded aversion'.
'edave' reversed gives 'EVADE'.
(Other definitions for evade that I've seen before include "Fail to pay" , "Dodge by cleverness or trickery" , "bypass" , "To get away from" , "Dodge by cleverness (5)" .)
