Don't go for support (4)
I believe the answer is:
stay
I believe this clue is a double definition.
'don't go' is the first definition.
(I've seen this before)
'for support' is the second definition.
(stay is a kind of support)
(Other definitions for stay that I've seen before include "Temporary residence" , "Remain - support" , "Stanchion" , "Delay (execution)" , "Wait" .)
