Tease or ridicule (3)
I believe the answer is:
rib
I believe this clue is a double definition.
'tease' is the first definition.
(I've seen this in another clue)
'ridicule' is the second definition.
(I know that ridicule can be written as rib)
(Other definitions for rib that I've seen before include "Supporting structure" , "Curved bone joined to the spine" , "Tease good-naturedly" , "Cut of meat" , "Part of vault" .)
