United Nations food measure still on the table? (7)
I believe the answer is:
uneaten
'still on the table?' is the definition.
(I've seen this before)
'united nations food measure' is the wordplay.
'united nations' becomes 'UN' (synonyms).
'food' becomes 'eat' (I've seen this in other clues).
'measure' becomes 'en' (typographical measure).
'un'+'eat'+'en'='UNEATEN'
(Other definitions for uneaten that I've seen before include "Left after dinner" , "Make an outline of" , "still on the table?" , "not chewed" , "Not consumed as food" .)
