A stall (5)
I believe the answer is:
booth
'a stall' is the definition.
(I know that booth is a type of market stall)
This is all the clue.
(Other definitions for booth that I've seen before include "Temporary structure eg for voting" , "Cubicle - Salvation Army founder" , "Market stall - Lincoln's assassin" , "Kiosk" , "Market stall; small shop" .)
