Get up before ten (4,3,5)
I believe the answer is:
beat the count
'ten' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'get up before' is the wordplay.
I cannot really see how this works, but
'get' could be 'be' ('get' can mean 'come to be') and 'be' is located in the answer.
'before' 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 beat the count that I've seen is " Survive a knock-down".)
