On reflection, mute vocalist revealing desire (5)
I believe the answer is:
covet
'desire' is the definition.
(I've seen this before)
'on reflection mute vocalist revealing' is the wordplay.
'on reflection' is a reversal indicator.
'revealing' indicates a hidden word.
'tevoc' can be found hidden inside 'mute vocalist'.
'tevoc' backwards is 'COVET'.
(Other definitions for covet that I've seen before include "Complacent" , "Hanker after" , "Jealously desire" , "Desire (often someone else's property)" , "Wish for something" .)
