Make novel Christmas break? (4,4)
I believe the answer is:
take five
'break?' is the definition.
(taking five is a kind of breaking)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for take five that I've seen before include "jazz number" , "Invitation to break" , "Enjoy the rest!" , "Leave one of half a dozen" , "Have a break (colloq.)" .)
