New hotpot for old eccentric, overjoyed (2,3,2,3,5)
I believe the answer is:
on top of the world
'overjoyed' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'new hotpot for old eccentric' is the wordplay.
'eccentric' indicates anagramming the letters.
'new'+'hotpot'+'for'+'old'='newhotpotforold'
'newhotpotforold' anagrammed gives 'ON TOP OF THE WORLD'.
Can you help me to learn more?
(Other definitions for on top of the world that I've seen before include "Elated" , "happy" , "Penguins aren't" , "as a successful North Pole expedition?" , "as a polar bear, but not as a penguin?" .)
