Turn up and sell a potty in perfect condition (2,4,5)
I believe the answer is:
ne plus ultra
'perfect condition' is the definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'turn up and sell a potty' is the wordplay.
'and' is a charade indicator (letters next to each other).
'potty' indicates anagramming the letters (potty can mean mad).
'turn'+'up'+'sell'+'a'='turnupsella'
'turnupsella' anagrammed gives 'NE PLUS ULTRA'.
'in' is the link.
Can you help me to learn more?
(Another definition for ne plus ultra that I've seen is " State of perfection (Latin)".)
