High street dead around lunchtime? (6)
I believe the answer is:
stoned
'high' is the definition.
(on drugs)
'street dead around lunchtime?' is the wordplay.
'street' becomes 'st' (abbreviation).
'dead around lunchtime?' becomes 'oned' (I can't justify this - if you can you should give a lot more credence to this answer).
'st'+'oned'='STONED'
Can you help me to learn more?
(Other definitions for stoned that I've seen before include "put to death" , "with jewels" , "on a trip" , "Like Olive perhaps" , "attacked with missiles" .)
