Make a tear in (3)
I believe the answer is:
rip
'make 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 "found on grave?" , "Shred" , "comment on one passing" , "Letters usually seen on gravestone" , "Tear (e.g. cloth)" .)
