Accident sees pulpy material put in drink (5-2)
I believe the answer is:
smash-up
'accident' is the definition.
(I've seen this before)
'pulpy material put in drink' is the wordplay.
'pulpy material put' becomes 'mash' (I can't explain this - if you can you should believe this answer much more).
'in' is an insertion indicator.
'drink' becomes 'sup' (to sup is to drink).
'mash' placed into 'sup' is 'SMASH-UP'.
'sees' is the link.
Can you help me to learn more?
(Other definitions for smash-up that I've seen before include "Serious collision" , "Road accident" , "vehicle accident" , "Violent road collision" .)
