Support for the others (4)
I believe the answer is:
rest
I believe this clue is a double definition.
'support' is the first definition.
(e.g. a shoulder rest is a support for shoulder)
'others' is the second definition.
(I've seen this before)
'for the' acts as a link.
(Other definitions for rest that I've seen before include "Relax with residue" , "What's left over" , "idle" , "still holding it" , "Relaxation" .)
