Set up stall (5)
I believe the answer is:
stand
I believe this clue is a double definition.
'set up' is the first definition.
(thesaurus)
'stall' is the second definition.
('stand' can be a synonym of 'stall')
(Other definitions for stand that I've seen before include "Support" , "Platform; attitude" , "partnership" , "Rise; bear" , "Tolerate; rise" .)
