Keeping cool when surpassed by (2,3,5)
I believe the answer is:
in the shade
'surpassed by' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'keeping cool when' is the wordplay.
I cannot quite understand how this works, but
'cool' could be 'in' ('in' can mean fashionable or cool) and 'in' is found within the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for in the shade that I've seen is " Outplayed".)
