Cuppa on Everest? (4,3)
I believe the answer is:
high tea
'cuppa on everest?' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'cuppa on everest?' is the wordplay.
I cannot really understand how this works, but
'cuppa' could be 'tea' (informal term for a cup of tea) and 'tea' is located in the answer.
'on everest?' could be 'high' (I've seen this in another clue) and 'high' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for high tea that I've seen before include "A lofty kind of evening meal" , "Late-afternoon meal" , "Early-evening meal" , "Early evening meal" , "Late afternoon meal which includes a cooked dish" .)
