Where the younger person goes out to lunch? (5)
I believe the answer is:
potty
'where the younger person goes out to lunch?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for potty that I've seen before include "Where youngster goes" , "Daft (informal)" , "Where kids go" , "sort of chamber?" , "Nuts" .)
