Epitaph to cause a tear (3)
I believe the answer is:
rip
I believe this is a triple definition!
'epitaph' is the first definition.
(rest in peace)
'to cause' is the second definition.
(rip is a kind of cause)
'a tear' is the third definition.
(I know that rip is a kind of tear)
(Other definitions for rip that I've seen before include "Severely criticise" , "Tear (e.g. cloth)" , "Tearaway" , "Tear violently" , "Letters often seen on gravestones" .)
