Put a tear in (3)
I believe the answer is:
rip
'put a tear in' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rip that I've seen before include "Letters appended to writing on gravestone" , "Tear or split open" , "Tear, rend" , "Louche character" , "parting message" .)
