Stable division (5)
I believe the answer is:
stall
'stable division' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stall that I've seen before include "Hedge" , "Animal compartment" , "Section of a stable and theatre" , "Delay - booth for selling goods" , "Postpone what one should be doing" .)
