Drunk a little soup. Like some potatoes? (7)
I believe the answer is:
smashed
'drunk' is the definition.
(I've seen this in another clue)
'a little soup like some potatoes?' is the wordplay.
'a little' suggests taking the first letters.
'like some potatoes?' becomes 'mashed' (I've seen this before).
The first letter of 'soup' is 's'.
's'+'mashed'='SMASHED'
(Other definitions for smashed that I've seen before include "Broke into small pieces" , "Broken in pieces" , "Broke into sharp pieces" , "completely sozzled" , "bust?" .)
