The others have a nap (4)
I believe the answer is:
rest
I believe this clue is a double definition.
'the others' is the first definition.
(I've seen this before)
'a nap' is the second definition.
(thesaurus)
'have' is the link.
(Other definitions for rest that I've seen before include "Remainder; be inactive" , "Support for putting things on" , "Lie down" , "Take one's ease" , "still holding it" .)
