Drink tipped on a large artwork (5)
I believe the answer is:
mural
'artwork' is the definition.
(I've seen this before)
'drink tipped on a large' is the wordplay.
'drink' becomes 'mur' (I can't justify this - if you can you should believe this answer much more).
'tipped' is a reversal indicator (letters tipped over).
'on' means one lot of letters go next to another.
'large' becomes 'L' (eg in clothes sizes).
'a' put after 'l' is 'la'.
'la' reversed gives 'al'.
'mur'+'al'='MURAL'
Can you help me to learn more?
(Other definitions for mural that I've seen before include "Wall art" , "Artwork" , "Wall design" , "Large wall painting" , "Painting on a wall, fresco" .)
