Take a break; remainder (4)
I believe the answer is:
rest
I believe this clue is a double definition.
'take a break' is the first definition.
(to have a rest is to take a break)
'remainder' is the second definition.

(Other definitions for rest that I've seen before include "Lie down" , "Surplus" , "Slumber" , "Remainder; be inactive" , "Inactivity" .)
