The others relax (4)
I believe the answer is:
rest
I believe this is a double definition.
'the others' is the first definition.
(other people are the rest)
'relax' is the second definition.
(to relax is to have a rest)
(Other definitions for rest that I've seen before include "Settle" , "Pole in Crucible?" , "Repose, others" , "Surplus" , "Remainder; relax" .)
