Thrilled to be at northernmost point? (2,3,2,3,5)
I believe the answer is:
on top of the world
'thrilled to' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'at northernmost point?' is the wordplay.
I cannot really see how this works, but
'at' could be 'on' (location) and 'on' is found in the answer.
'point?' could be 'top' (top is a kind of point) and 'top' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'be' acts as a link.
Can you help me to learn more?
(Other definitions for on top of the world that I've seen before include "as Hillary once was?" , "as a successful North Pole expedition?" , "Delighted" , "Penguins aren't" , "happy" .)
