The remainder take it easy (4)
I believe the answer is:
rest
I believe this clue is a double definition.
'the remainder' is the first definition.
('rest' can be a synonym of 'remainder')
'take it easy' is the second definition.
(I've seen this before)
(Other definitions for rest that I've seen before include "Settle" , "Take it easy, have a break" , "Relaxation" , "Surplus" , "Inactivity" .)
