Young woman expecting to be wasted (8)
I believe the answer is:
misspent
'be wasted' is the definition.
(I've seen this before)
'young woman expecting' is the wordplay.
'young woman' becomes 'miss' (title for a young woman).
'expecting' becomes 'pent' (I can't explain this - if you can you should give a lot more credence to this answer).
'miss'+'pent'='MISSPENT'
'to' is the link.
Can you help me to learn more?
(Other definitions for misspent that I've seen before include "Dissipated" , "having used money unwisely" , "youth? Sort of" , "troublesome youth?" , "wasted away?" .)
