Some raver trying to turn away (5)
I believe the answer is:
avert
'turn away' is the definition.
(synonyms)
'some raver trying to' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'AVERT' can be found hidden inside 'raver trying to'.
(Other definitions for avert that I've seen before include "Deflect away" , "Turn aside, prevent" , "Ward off (bad event)" , "With prominent incisors" , "Fend off" .)
