Childish place to put food and drink (3)
I believe the answer is:
tum
'drink' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for tum that I've seen before include "Stomach (informal)" , "Belly" , "Middle" , "Corporation" .)
