Rend, tear (3)
I believe the answer is:
rip
I believe this is a double definition.
'rend' is the first definition.
(I know that rend can be written as rip)
'tear' is the second definition.
(I know that rip is a more specific form of the action tear)
(Other definitions for rip that I've seen before include "Tear (e.g. cloth)" , "Tear, rent" , "Letters usually carved on gravestone" , "death wish" , "Tear; gravestone letters" .)
