Short staff (4)
I believe the answer is:
cane
'short staff' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cane that I've seen before include "Beat - bamboo - stick" , "Slender support, for 32 across say" , "Rod for beating" , "Walking stick; punish" , "Strong, flexible stem" .)
