Frittered away (6)
I believe the answer is:
wasted
'frittered away' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for wasted that I've seen before include "Used unprofitably or lost weight" , "Frittered away" , "Squandered or withered" , "Used up needlessly or weakened through illness" , "Dissipated; atrophied" .)
