Tolerate stall (5)
I believe the answer is:
stand
I believe this clue is a double definition.
'tolerate' is the first definition.
(I know that tolerate can be written as stand)
'stall' is the second definition.
(I know that stall can be written as stand)
(Other definitions for stand that I've seen before include "Tolerate - resistance" , "partnership" , "Be upright; base" , "Sit here at a sports event" , "Assume an upright position" .)
